I've heard that it is not uncommon for people with mental illness to have difficulty holding a job:P But it's no guarentee^_^ I have a lot of problems with depression, anxiety, racing thoughts, paranoia and hearing voices; I have problems with school that I'm stuggling with, but my work isn't really effected
I've been to workshops to help with writing resumes, and handling interviews to help me out too. So it's not hopeless.
But I'm sure if you're having a lot of trouble with work your doctor can have something arranged for you.
Hope this helps!
