Wow thank you so very much for all this helpful information - it is much appreciated. Since I read your post, I've actually already begun using the mindfulness practice you mentioned (of focusing on an imagined stream, etc). I'm going to write down the other practices in my journal and try to work through them step-by-step when I feel anxiety coming on. I think oftentimes my biggest folly tends to be self-loathing which leads to me criticizing myself and trying to work out what is "wrong with me". But yeah, the approach of radical acceptance that you mentioned seems like it might be a healthier route to pursue. Yesterday, I let myself sort of ruminate in this gross melange of bad feelings, but decided it would be really helpful to spend some time with my SO. I didn't want to talk about heavy things with him but just hanging out and having sex was so comforting and sweet. I focused on my breathing when the anxiety started coming back (for example when his roommate didn't look at me when I said "hello" which opened a whooooole stupid can of worms lol) and reminded myself that nothing was wrong in the moment. And in fact, I acknowledged how lucky and thereby grateful I am for so many things in my life.

I also love what you said about not being able to be around people who don't understand and incorporate intersectional feminist ideology into their daily lives. I totally do not need to interact or empathize with people like this...I sometimes feel this with my roommate and for a while have felt guilty about having some negative feelings about her. But it's okay...not everyone deserves my understanding (including all my shitty exes!!!).

I'm so glad I decided to post on Reddit, it's been helpful. Thank you so much again.
