Feeling guilty for being anxious

So I checked out this local DSA (Democratic Socialists of America) thing, a branch of it in my area, because I heard they organize, and they do protests and such. I've been feeling guilty about not doing things to help people, because of the state of the world right now

I got into it, partly, joined the *** server, maybe I could ease myself into things, and I've had maybe one or two interactions with people. I just feel like such a coward. I know I'm being too hard on myaelf about this, but I joined because I wanted to do something, and now I'm just having difficulties because like, they hold events, and I'm anxious about them, like what if they get frustrated with me for not going to these events?

I think it's just anxiety, and I'm overreacting a bit, this stuff just feels so difficult and my brain makes me feel like a bad person for not doing more
