Hi, I just saw your comment while I was reading through and it sounds so much like me. I also question the concept of illness.

Have you heard of "The Work"? If not, check it out. The Work | The Work of Byron Katie. Or search byron katie on youtube. She has like a six step thought process for relieving depression. Meds and therapists didn't work for me. "The Work" was my answer to depression, and it's so simple and easy. It's not so much theory as actually a step by step process that you can do. I'm so glad to be happy now, I just keep telling everyone about it.
