Left my part time job due to anxiety. LCW. Will I be sanctioned?

Hi everyone I am new to Scope and hoping for some support.

I am at the end of my tether dealing with my mental health. I have been on LCW for over 6 years due to anxiety, depression and suspected ASD. I struggle with social interaction with strangers and leaving my home alone, but last year I managed to get a small part time job. I mainly took this up because I was really struggling to live on UC and felt I had no choice. I found it actually improved my mental health a bit for a few months due to having a routine, but then I began to decline. I was being taken to work every day by a dear friend, but they can no longer do this. The office I worked in also began to get more busy, and the people got more chatty. The last few months I've been hiding in the toilets a lot and having a lot of physical symptoms like sweating and shaking. I made the decision to hand my notice in and am leaving this week due to these reasons.

Will this affect my UC and will I be sanctioned? The only benefit I got from doing this small amount of work was that UC was mainly leaving me alone. I am now terrified they will start forcing me to do lots of interviews and work commitments, or making me come to the JC. I actually had a phone appointment with them today, and couldn't bring myself to say I am leaving my job. They also booked me in for a 'Work Search review' appointment at a jobcentre when I am always offered Video or phone appts, and I assume on LCW no work searching exists?. Even these Phone appts leave me in a state. I have to write prompts and a script of sorts to be able to chat with them. I shake and often cry afterwards. I'm very poor at articulating myself so I'm stressing myself out with thinking how to approach the fact I've left my job and how to get this work search review changed. I'm very poor at articulating myself and advocating for myself.

Been on a wait list for ASD assessment for over 6 years. Doctors just throw different pills my way. I'm really struggling. I just wish I wasn't forced to do any of this, it is really affecting me. Any advice will be very much appreciated.

Sorry for rambling. I haven't got many people to offload onto.
