I was not away from work for as long as you but I took off work for about a year or more due to anxiety. When I went back, I did as you are planning - I took a less demanding position. Going back was difficult but it did help to return to a job with less stress. I also had a good counselor and I joined a support group, both of which were very helpful in getting back into the world of work.

All along I felt it was important for me to at least give it my best shot to return to work or find something meaningful in my life for the very reasons you mentioned - not only money but also self-esteem, accomplishment, socialization, etc. I understand where you have been and why you want to go back to work. I hope you find an opportunity that feels right to you.
