I was just like you, I’d struggle to make friends and tried too hard to be funny and cool to make them. The best advice is to just be confident in yourself, or stop putting yourself down for the most part. When you are yourself and content with who you are you won’t be upset anymore and will soon find friends who accept you for who you are. And once you find one person who genuinely enjoys you and your presence you’ll easily find other friends, or maybe that one person will be good enough. Just be you and do what makes you happy, there are other people out there who may share a lot of the same interests and traits, all you gotta do is be true to yourself and be patient. You can DM me and we can talk more and maybe I can be the first of your soon to be friend group.
