Absolutely love, I think I've never been shy really but I've shared this feeling you've got of anxiety and fear that my interactions with other people might go so wrong. Used to happen to me because I wasn't sure if I was someone they would like, and my asocial tendencies might get in the way of anyone liking me. Not only that, at some point I convinced myself it wasn't worth trying cause they were probably bad people and would laugh about me. But I'll tell you what, I went to this sort of spiritual retreat with other tenagers at the time, and the woman who was leading it always told us something that seems obvious but that I never really understood until that point, and it was "Opportunities belong to those who take them" if you don't take the opportunity what face do you have to complain?. I ain't lying when I say it changed my life. Because then every time I saw someone I really wished I could talk to I would remind myself that the opportunity was there, beyond the fear and everything, it was there waiting for me. The next thing to learn was to get used to rejection, it sounds awful but the more you hear the word No, the less limiting it is, the less scary. You can't imagine how beautiful it can be for someone else to feel you found them so interesting and worthy of your time even without having met them yet. And finally, start small, give a compliment, set the base for those people you want to meet, let your face be familiar to them, next time you might smile at them, and when it feel comfortable go and say hi, make small talk, tell them what you found nice about them and ask if it would be okay to have their socials, maybe you'll create a bond steady enough to ask for a coffee date or meet up.
wish you the best of lucks XOXO
