I don't have any great advice for you but I wanted to tell you I totally understand. People have generally liked me and for some reason feel very comfortable with me. After knowing someone an hour or so they end up telling me thier secrets, life stories or asking for some sort of help with some situation. I have made lots of friends in my life but most don't stay. They say a friend for a reason a season or a lifetime. I have a hard time with the lifetime. Everything seems fine and suddenly they get mad, fade out or just dissapear.
People seem for some reason to admire me for the person I am and it makes them feel worse for the person they are. I don't put that out cause I think I am open, honest and non-judgemental. The thing is they may think I am "close to perfect" but I try really hard to be the person I am and to treat people well. I can't imagine that I have to be thoughtless, uncompassionate or mean just to keep good friends.
I don't know if this helps at all. I just intended to say I understand but then all this comes out.
As for the boring or stupid, maybe it's because your a little shy and uncormfortable and since your kinda quiet people aren't "noticing" you so much. No your fault at all, if that's how you are. Not everyone can be the life of the party.
I am very much a people person but I live in another country where they speak another language so I get the same thing, because I can't participate people forget I am even there and it makes me feel not fun and boring and sometimes stupid. I have to keep reminding myself I am not but it is hard.
Keep reminding yourself that you are not boring or stupid. Maybe it's just a crowd that you don't mesh well with r have so much in common to talk about.
I am gonna shut up now!! If you find any secrets to making good friends let me know!!
