No words to describe how i feel after Pip results..

Hello, my name is cathal and I am a 27 year old living with aspergers with severe anxiety and depression.  I was told I was entitled to pip as I was originally being allowed DLA. 
I have always wanted to work and progress in a career but could never hold down a job due to my personal issues understanding and communicating with people  i find dealing with the public extremely stressful and feel like I am being judged 24/7. 
I think some of these issues were as a result of my upbringing and a bullying child hood. 

Anyway I was awarded DLA after easement many years ago and was told due to my mental illness I would always get it and not to worry . This wasn't an excuse as I still always wanted to work and have been constantly searching. But when i was told I had to apply for pip I freaked out. My sister has a rare condition with her pancreas and has been battling her whole life with it. Through multiple operations etc her pip assessment was horrible the lady entered her home where she picked apart everything she was doing she purposely held out a book for her to read to see if she could lift her arms above her head. For one example .

Anyway the lead up to the assament was stressful as every one is. But it didn't help they booked me in the day right after boxing day so i could not enjoy Christmas with my family with the worry. The night before i did not get a wink of sleep i left the house in tears as I get bad nausea from the anxiety and the anti depression tablets were not helping. Sometimes they do and sometimes they don't. My interview went ahead as planned. The lady seemed nice and she told me not to worry she was just checking details and it wasn't up to her little did I know she recorded and analysed every single thing I did. I was to nervous to speak I could just about get my words out which was why I brought my mum. 

The next part is what really frustrates me.. I received my result this week and I was awarded 0 points!! Apparantly there is nothing wrong with me. Fair enough I'm not in a wheelchair or dieing but no points seriously??? 

I explained I lived on rice and gravy when i tried living by myself and sometimes I would forget to eat and she said i could easily prepare a meal and has not diet problems.. 
I explained the tablets made me gain weight and she said i looked well nourished 
I explained I had severe anxiety and can often misunderstand people details and money and she said i understood  evertyhing being said and seemed intelligent whatever that meant. 
She said i have no problem with transport and driving around even though i dont drive I prob never will as I'm terrified of being behind a wheel and I won't go somewere I dont know i try and walk everywere. 
She also said i was able to use my upper limbs freely even though I wasn't complaining I had physical problems. 

She finished off by saying my mental state was fine..now what the ****. I hadnt shaved in a while I had bags under my eyes . My knees were shaking and I was trying to hold it together plus I'm on Anti anxiety meds... 

Someone please tell me. Do i really deserve nothing? I'm so distressed and have fallen out with my mum over it and don't know who to talk to. She thinks I'm no were near as "ill" as my sister so i shouldn't get it. I dont know.. Should I just give up?? Help
