You have a lot going on there, and while I can certainly understand it from a chronic pain standpoint, seems to me you could use some soothing words from our friends in the depression forum. If nothing else, don't dwell on the bad. There is a certain level of depression in all of us, but by coming here and taking the time to type what we are feeling shows that we (and you included) are not giving up. The response is amazingly understanding and if you give it a chance, you can see what a family it can be here.
If you do not feel that your Dr. is listening and is more concerned with the issues of where you live than with how you live, I would suggest it is time to find a new Dr. Do not give up, there are always other options.
Best wishes for a better day tomorrow!
