I'm sorry you're feeling this way. I can relate, somewhat. Can I ask, how old are you? (you can give a range). I'm 34 and I haven't felt like you described since high school. Anyone of any age can feel this way, and you should seek professional help, but I believe TRUE friends are hard to find and this MAY be just a phase for you. You'll find those you click with! Try developing your own interests and hobbies (as opposed to just always joining others). And, assuming they're legal and non-hurtful hobbies, stick by your choices and defend them.

In high school, I was soooo into anime. I still sort of am. I never once said it was "weird" or "dorky" like other people, because I focused on what I liked so much about it: the theme songs lifted my spirits, characters I could relate to showed me how life could get better, and I learned about Japanese culture along the way which paid off when I went to Japan!

It'll get better. Have hope.
