I know that feeling. I'm aware it's mostly in my head and just part of anxiety. Still it can be a challenge. I think you're profile, and posts are interesting, interactive, and most anyone wouldn't find you annoying on here one bit!
I have a platter that says, “Never let your ability to annoy exceed your value as entertainment.” In all areas of life, maintaining the proper balance is key. First, be yourself without apology. Second, pay close attention to other people. Good luck in meeting others with whom you connect deeply.
Well to be fair, I wanted to say that I don't you or your situation but it may not be you, it could be the other person's insecurities too. You always got to take that into account. Sometimes other people can make it seem like it's you but sometimes it's just the way the other person takes things. Not your fault and can't please everyone.
Also, I get the same thing. Sometimes you just can't care, life is short. I'm 36, when you get to a certain age you look back on things and wish you hadn't care, like trust me 100%.
Everyone says dumb stuff at some point, it's not like there's something wrong with you; honestly the whole world has gotten harder and more painful lately for everyone and people are a lot more harsh with each other and less patient; if you ever read Revelation in the bible it's literally how it's written there
