When I was first disabled, I didn't isolate on purpose. All my time and energy was spent in trying to get well (I was in denial, and had no one to help me at first (long story)) It wasn't till after it began to set in that I was permanently totally disabled. I needed time to figure some things out, and though I never stopped going to physical therapy nor to my psychologist, I isolated myself from the rest of the world. (Family had left on their own.) I took 5 years "off" from society. Even now though I'm trying to be and do like others, it just doesn't always work for me.

I can't do "anything" I used to before the accident. To complicate things, I used to do "everything." (Well, I never jumped from a perfectly good plane, or dived in a submarine, but you get the idea.) I am still looking for something I can do well, have fun at and rely upon as a hobby for the remainder of my life. Alas, due to my pain and fatigue factors, it will never be something I can do all the time. Nothing is.

I don't recall how recent you realized your situation is "permanent." But imo you are "allowed" a time of self pity, it is a mourning process, you have lost many things, not just the ability to do what you used to, but you have lost the hope of doing other things too. Mourn if you must. The sooner you can pull out of that mood, etc, the better for you. But don't rush it. If this is recent, then I would say you might need a different T, someone who is expert in pain and stress management etc... someone who truly understands. Encouragement is good, but you have to be ready for it.
