What am I supposed to do?

So I've been signing on for the last year and still have not got a job. I've done 2 training g course which did not help either. I've had so many work coaches the recent one was the worst. She kept mentioning my social anxiety but clearly didn't understand what it is because she was saying I'm being picky when she was showing me school admin jobs which I said I'm not looking for, a school would be a noisy environment and id have to interact with parents, students as well as colleagues which wouldn't be good with my social anxiety. I have a quiet voice too so no one would hear me. I managed to get an interview for a job that would either take 3 hours to get to with 3 buses or 1 hour with a train and a bus which would be £19 something a week which would add up to around £400 a month if I worked 5 days a week. I ended up cancelling it there was no point if I did get the job I would not be able to pay that much when the wage probably would have been around that much or not much more. She said you will have saving when you have a job like how if I'm spending £400 on travel there won't be much left over idk how much the wage would have been and it was only temporary for 12 months anyway. At least I'm having a different work coach next time and hope I never have her again, I only had her twice and she already made me increase the amount of jobs I have to apply for to 18 every 2 weeks when I'm lucky if I find half of that.
I hate it so much, whenever I have a nice work coach they leave and I end up with a rubbish one like her. They don't even help and want me to apply for jobs that someone with social anxiety, introverted and quiet would not be able to do like bar work, school admin like if I can't do it I'll either not get the job, get the job but get fired or quit. She just wanted to make herself look good. I'd rather have a job in the background like a small quiet office or remote work working alone or in small groups not these loud places they want me to do. I'd rather have a job then go to the jobcentre every 2 weeks to be looked down upon and lectured. I have no choice, if I don't go I'll have no money to live off.

If you have trouble with a work coach, then could you not take it up with someone higher up at the job centre?
Keep on applying for jobs though. You will get one eventually.
I know you dont want to do certain jobs because of your social anxiety, but would doing jobs that are outside of your comfort zone actually help you in the long run?
