I hope the an adjustment will help. I understand about anger and wanting to just walk away from everything. I also understand about feeling trapped. I don't really think I would be happier if I threw it away but sometimes I just feel trapped by the rigidness of everything.
I discovered some truths for me. I was also off work for two years. I learned that when my life really was simpler, it was easier for me to slide into my depression. The very structure and rigidity that I think I hate also keeps me functioning. It makes me get up, put one foot in front of the other, and be productive. I don't make good use of the free time I have.
Good luck and I hope you find a happy place again soon.
