What Man says makes sense. Perhaps, your expectations of people are very high.
Think that they are not much moré different than you.
I'm also having troubles with people now that I'm moré open up them. So, I think you hate fakes, falseness. i also hate it.
There are also people who are truthly. These are the ones who are worthy.

What can I tell you? I don't want you to put on a rose-coloured glasses. Take with the possitive of each person. There will be some you will share a couple of laughs with, there will be others you will have as good colegues and you will share about work tópics with, there will be other who give you an intelectual encouragement, there will be other who give you affection and became true friends. Some of them will be with you only for a few minutes, other will spend the life with you.

Don't know if I am giving you some helpfull input. Sorry if not.
