Similar situation here. For me instead of a 9-5 keeping me busy, it's my state of health being a constant obstacle in daily life. Most organizations have no set way for new members to get familiar, making it even harder for me to find my bearings. Let alone physically ever attending meetings etc.
Online I tried to get in touch to help with leftist media, but I was politely rejected after being upfront about my physical limitations.
Praxis for me now is just talking to friends who are left leaning, and continuing to educate myself. I just have little energy to do anything else, and it is frustrating.
You are not alone. I used to frequent the subreddit as well, and everything about China for example was removed or heavily censored against. It is most definitely a more demsoc or socdem community now, with some very reactionary views when it comes to AES and international solidarity.
I noticed more backlash and bolder stances from a handful of other regular ML's, but it seems like it won't matter much as we are a minority among the usual western ultra's and socdems.
All in all you're not alone, and I hope this message is at least some comfort. Things are tough, but don't despair.
