I empathize a lot with what you and others have said. Understand that some people are better at organizing in real life (and we always need more of those). But you gotta recognize your strengths and your limits too. Some of us are just better at educating and organizing online. The stuff we share with each other here gets dispersed in our conversations offline. That is still activism. Especially in the imperial core. Every conversation you have about communism is a brave thing to do and comes with personal risks -- whether that be your job, your friendships, your family, your livelihood. We're not at the point where people are randomly being imprisoned for thought-crimes yet, but we may be headed in that direction. Simply educating people where you can is still a courageous thing to do.
I have adhd, depression, etc. and I have also taken a back seat from being present in spaces. I've gone through the phase of being disappointed in myself for not "doing more." I forget sometimes that what I have is technically a disability and I need to treat myself with grace. What ultimately helped me was recognizing just how limited we are by our circumstances and by taking stock of all of the people in my circle that have been radicalized or have grown more skeptical of capitalism just by knowing me.
