Psilocybin-Bad trip still feeling effects 1 year later

One year ago I was on a very consistent meditation practice (shikantaza also known as zazen) and was developing quite quickly, I’ve been practicing this meditation for over 5 years and have seen its benefits. I come from a background of psychological disorders my grandma and grandpa both went through psychosis, depression, anxiety and some close relatives too. I went through a major depressive episode 6 years ago and used shikantaza to help me get out of it and it worked wonders. However, to get to the point, I had experience working with mushroooms to elevate my experience and insights but a year ago I was at a concert with a friend who is also like me, and typically I’ve always done mushrooms alone or with this friend in nature or other setting but this time I did it at the concert and it rocked me to my ass, I could hardly function and as the visuals enhanced (1 gram golden teachers) the mushrooms were essentially disrespected and so angered with me that they were punishing me so to speak. Since that day I developed social anxiety that links me back to that mushroom trip and I instantly feel what I felt on that trip, super anxious, heart pounding, stomach uneasy even at times nervous shits which is embarrassing but it is what it is), I’ve been meditating on and off but this social anxiety just doesn’t go away, I drink alcohol and it helps with liquid courage and all but I don’t want to rely on that I never used to. To conclude, I just want some advice on what I need to do next pretty much now every time I go out to social settings mentally I get dropped back into the mushroom trip and symptoms start again. Due to family history and the nature of my spiritual progress I typically have very vivid intense thoughts and dreams so life already feels like a low dose psychedelic, but I just need to find stronger roots and ground myself more.
