I also started from of place of feeling like anything, including volunteering, was well beyond my capabilities at the time. There have been times when my therapist has said "I don't know where to go from here". I think if I hadn't managed to take any steps she would have considered it unethical to continue helping me, though I know she would have still had my best interest at heart. From your previous posts it sounds like your therapist thinks you're capable of volunteering, but you were waiting for a breakthrough to happen before you felt able to take the first step. I know how hard it is when surviving life is hard enough without the added pressure of something like volunteering, but having made it out the other side, I also know how important it is to force yourself to do it anyway (or something similar), no matter how unready you feel. Even if it's just 30 minutes a week. At least for me the breakthroughs never happened until I forced myself out there, even though I wasn't ready, and even though it made me feel worse, and fall apart some days. Is there any way you can trust your therapist to help you make a step towards gaining back your life, by doing something like volunteering, and trust that she will be there to support you through it?

Sorry, I know that probably doesn't come across as super supportive. I just know how valuable a good relationship with a therapist is, and I feel that it's probably the most helpful thing of all. I don't want you to lose it if there's a chance you can allow her to help you to move forwards.
