Am I the negative/toxic energy?

These days it's like a whole freaking movement to keep "negative and toxic people" out your life and I'm tired of fucking seeing it in quotes and social media! Nobody is happy 24/7. I've been suffering with bipolar for over 10 years. I feel like I'm a negative person but I can't seem to "fake it till I make it" like everyone else. Anyway I'm friendless with no friends and have no family around. I look miserable all the time and unapproachable. Naturally I am an introvert and loner but at least once a week I'd like to have a friend to hang out with. I don't know how to manage friendships...I don't speak to my sister everyday and we're extremely close but it seem like with friends these days they want I to be up their ass all the time. Maybe I'm meant to stay friendless because I'm so fucked in the head.
