My anxiety

before I was five I loved life according to my parents but I h had an accident and I hit my head and I cried for an hour I went to a seizure that wouldn't stop they had to put me in the medically induced coma I was there for a few hours when I woke up all I can remember is hating life so hatred so burden it's awful and I'm tired of it and I can't handle it anymore. I've tried several type of therapies to get over my anxiety I just recently started back in therapy and he wants to do cognitive behavioral therapy because this is something I haven't experienced before myself hatred I've always thought it was depression but it's thought process and it's overwhelming and I don't know what to do. I've come up with a plan to help myself move forward and the anxiety is getting too much for me and I can't take it and I don't know how to handle it
