PIP for mental health refused because I'm a parent?

Firstly thanks to all the advice and support given. Especially since its xmas and you've still found the time and kindness to respond. Honestly I researched this massively, went on every official gov site reading all the guidelines, restrictions, descriptors everything. Even checked laws and regulations around how to assess descriptors and even how at tribunal laws and regulations on why a decision was found wrong and overturned. I took advice from various sources, including paying a "professional" to help with filling in the form. I read every post regarding assessor tricks and reasons for refusing. So I knew in advance that driving, pets, children and work seems to automatically dismiss claims for both physical and mental problems. Really thought I'd covered these areas with evidence well. As expected I was asked about driving and explained yes I can drive but hadn't done for a period of 8 months because of overwhelming anxiety and panic attacks. Had only recently begun driving again only when mentally able to and not very far. Surprisingly she never used this against me! I kinda giggled slightly when asked about pets cos I found it funny that they do actually follow this script. Anyway I have no pets. Like I said I knew the child and work would be a big factor used against me but really thought I'd evidenced enough to prove all the help and support I receive from family to help care for my child, during assessment i described my difficulties and cried about how guilty i felt that i felt i wasn't capable of being the best parent i should be for my child and told her how ashamed i was that my family had to regularly take my child to stay with them when my MH was so bad I felt unable to care for him adequately. Also the fact he is almost 10 yrs old so not exactly needing huge amounts of care and 24/7 attention required like a toddler or a baby. For work the fact I trued to detail everything about my attempt and failure to return to work because of subsequent worsening of my MH and that I was going to have to give up work. ALL IGNORED! Wouldn't care but my assessment should have been 4 weeks before but got cancelled after they ran out of time to start mine. If they'd done it on original date I wouldn't have even returned to work at that point so they'd have had to really focus on using my child as an excuse to dismiss me. Just really angry DWP are allowing these areas to be used against a claimant! Driving- if found to have high mobility you can get a mobility car! Work??!! Having a job doesn't affect PIP unless it contradicts your claim, the fact that I tried and failed to return despite my workplace putting a lot of reasonable adjustments in place should never have been refused to "I HAD RETURNED TO WORK THEREFORE" pretty much it means I'm cured! I've listened to the recording at least 3 times now to see where I could have gone wrong or not using the descriptors sufficiently. I've noticed that every time I tried to explain things in further detail she would talk over and interupt me, would move onto another question whilst I was still talking, she told me a few times that I was talking too much! And going into more detail than needed. Kept telling me what I'd said was all she needed and didn't need to know anything further. I did apologise for my nerves and anxiety making me maybe talking too much but she promised me it was enough and covered every answer fully and would let me know if she felt I needed to explain in more detail. She's obviously left out what I believe to be important details but I also think she kept trying to prevent me from explaining my point further. She really only wanted yes or no answers a lot of the time without further explanation. I now feel like it was all a set up. This is where I'm struggling to figure out how to successfully challenge the decision because I used every piece of evidence I could and really focused on proving these particular areas as I knew they would be used against me. For MR I know my views that the assessment was flawed and won't be considered by the DM. I've thought about putting a complaint in to IAS about the assessor but after researching it unless I can find actual lies which they would probably view as omissions as it appears that the HP has every right to leave details out that they believe has no bearing and it comes down to their medical opinion on what to include. It's a difficult thing to prove I believe her opinion was biased and not based on assessing my mental needs. She did confirm in my report that I was tense, anxious, withdrawn had poor rapport and had some difficulty coping at interview (which i think was an understatement as she had to stop the assessment to calm and console me 2 times while having an anxiety attack). The only thing I could possibly accuse her of lying about is when she said noted in my mental state exam that I had adequate general memory and was able to answer every question in full without any input, when in fact there were several times I had a lot of difficulty remembering specific things like name of medication, dates of appointments or medication changes. I had no idea and couldn't remember these things. Told her this and expressed my efforts in trying to locate the the info she wanted by looking through various paperwork but still couldn't find it. I could eventually confirm the dose of medication I'm currently on by telling her I was going into the kitchen to get it and see. But as far as her wanting to know the date of medication increase and previous date of medication change and what the medication was previously I didn't have a clue! This went on for a good 10 minutes until I got so stressed and asked her if she had this info on my form or within the evidence I'd provided as I was sure I'd reported it all. She made a big huff about looking but actually within 3 seconds she had all the info in front of her! She told me the name of my previous meds and I said yeah that sounds familiar. I suppose her finally telling me and my agreement that it sounded right was enough to prove my good memory 😂She told me there'd been some change in my meds in Oct and asked me what that was. I didn't know. I couldn't remember dates of starting or changing meds at all. She kept pushing that a change had been made in Oct and what was it? I honestly didn't know I told her it could have been when my meds were changed or when the dose was increased but honestly didn't know. But still apparently no problem with memory. Strange that! Not sure if they'd find this sufficient to warrant a complaint 😦
