I don't really understand why
It's just I don't understand why people don't really seem to seek out friendship with me, and why they seem to start ignoring me after a while.
I feel like I've had so many friendships were I do so much for whoever, both materialistically and personality wise for them. Am I a boring person? Or simply too weird?
I also feel like when I meet new people these days, some people do obvious stuff directly in an attempt to hurt me. Without me having done anything just as we meet, some people just try to push me down immediately. Implying I'm stupid, not this or that, and more in an obvious way...
@Hyeonsil I'm so sorry that people have been doing this to you! 
It really hurts when you put a lot of effort into a relationship, and it doesn't seem that they're giving anything back to you. Please know that you are deserving of love and of happiness 
I have faith that you will find wonderful people who love you for who you are- you don't have to change yourself for anybody! It's their loss if they can't appreciate the lovely, wonderful person that you are. Please know that we're here for you, and that things will get better. You're an amazing person, and this is no fault of yours
Yeah I've had experience with that too. People have said that I'm not flexible enough, I'm too depressing, too serious...and I'm sure that I'm also too awkward and boring... Eventually I learned how to detect when someone wasn't serious about caring or wanting to spend time with me...and eventually I just stopped trying to make friends..
