Social Anxiety Running My Life

I have social anxiety and I am really struggling currently. When I was younger, I was a rambunctious, outgoing kid but I was excluded a lot and bullied through middle school. I got more quiet and introverted over time. I struggled to make friends my whole life but especially since starting college. I’m really proud of how much I’ve accomplished despite my constant anxiety surrounding social interaction and relationships. I have 4 really great friends and a boyfriend who is very sweet. I guess I’m on here because I’m just so sick of the constant narrative in my head telling me that I’m messing everything up and that I am “abnormal” or “unworthy”. I am working really hard to develop a sense of confidence in myself by doing things that I feel confident doing (yoga, hiking, reading, etc) but every time I say something or text something I deem awkward or weird I just come down on myself and tell myself this is why I was alone for so long. I don’t know how to work through this and have confidence in my interactions with other people.
