Within the last 12 months my life has changed quite dramatically, I started a new job last year in the career direction I've been wanting for quite a while. I started the job and struggled to fit in with the people I was working closest with, not getting training I needed, being given mundane tasks unrelated to my job, and then being consistently ignored by my colleagues and told not to give my opinions and ideas so much. 10 months down the line I left the job as it stopped me sleeping, destroyed all the confidence I started with, and ultimately has me questioning my entire life and has given me the worst anxiety I've ever had. It stopped me sleeping, made me panic every Sunday night before the start of the new week. Having left I started to relax and become myself again 1 month off and I felt normal again. I've recently started doing a few trial weeks in the same field but I find myself terrified still every Sunday and when I get to work I just want to run away. I don't know what I can do to stop this, the people at the new place are actually nice to me and are training me but im just so scared of screwing up and having people be horrible to me that it's made me question if I want this career at all.
Does anybody have any advice to counteract these feelings? I've never felt more lost in my entire life.
