I understand, I think, what you're saying.
I often feel stuck in my own head and terribly, terribly antsy. It's hard to get out of my head--in a good way, that is. I want to stay as busy as possible. As someone who's been unemployed for a short while, that's difficult. So, I do a fair amount of volunteer work. Sometimes it makes me feel better, and I feel that I've helped someone, even if just a little bit. Sometimes I don't feel I've done much at all for anybody. But then I get abundant thank yous, and I realize that I'm just not giving myself any credit. Or, as a friend of myself says, "Sometimes, when you're feeling really down, you just don't have a lot to give." How true.
But I do recommend volunteer work as a way of getting out of one's head in a positive way. Give it a try. (Of course, you may well be an employed person who's working long hours, and this may not be an option for you.)
Sometimes the meds we're on make us antsy. Talk to your doctor about the antsiness. He or she may want to adjust your meds.
I don't know if any of this helps. Please know I'm thinking about you.
