Style advice?

This is probably going to sound really weird and im not looking for reassurance or anything but I'm super insecure and I have really bad social anxiety to the point I cant handle going out in public in anything besides like the same 4 or 5 outfits that I have reserved because I get soooo anxious and scared of what someone might think. But I was wondering if anybody could possibly recommend a way for me to overcome this fear by like slowly changing and introducing new things to my style? because right now my "style" is non existent and it just consists of a few baggy shirts, long sleeves, bracelets, and boot cut jeans. So if anyone has been in a similar situation or can recommend small accessories or clothes that don't stand out a lot that I can slowly introduce that would be like really amazing because I really want to open up my options and actually express myself in a way that im comfortable with.
