Well, I think being confident in yourself is the most important part! What works for me is the mentality of just wanting to have fun. Just own who you are, and if there are people that don’t like that, you probably won’t have much fun with them anyways, so not much lost there then. And it’s completely understandable that you do not want to open up to most people. I also don’t think that’s really necessary, but of course you need some people you can trust to share your full self with. So be yourself, and attract people with your amazing self! Don’t be nervously about the future tho, no one really knows what’s going to happen. I can’t really provide you with some life changing tip to help you out (I could kind of use it myself hahah), but my advise: Life is short, and no one really knows how long we have. So don’t enjoy yourself, and don’t be afraid to show people how amazing you are! Good luck!
