I feel bad I don't have a career either. My health took that from me. I kinda feel I'm worse off not having a job but I can't take care of my daily needs as is. I would go to the interview and try. If you can't do it then you'll know that your stability is to fragile to work. Have you talked to your treatment team about going back? can you do part time? I have a young adult and I'm sitting here thinking now what. I know I'm not healthy enough to work even to volunteer but I want to do something with my life. So whatever you choose to do know your not alone in this feeling.
