Do you know what makes it seem so hard?

I have also really got a lot out of doing things like that. Voluntary work has helped me so much and I really love working with older people. I know it can seem daunting or unhelpful when things aren't good, though.

Maybe you could start with some of the things that seem doable and build up to harder things. You also don't have to do everything your psych suggests if you don't think it would be helpful for you personally, I guess it's just a case of finding activities that will work for you.
