I used to have a group of friends that was really good for me and my mental health and I really did enjoy spending time with those people, but during the past year there have been many changes in our lives, universities, jobs and partnerships... and I lost touch with them.

I find it very hard to find new friends and to open up to new people. I am naturally more quiet and introverted and it's always been a challenge for me to find friends, but I am also the sort of a person that don't like loneliness even a few days spent alone are psychologically very draining for me.

The issue is that even though I go out and meet people, I always feel like I don't belong there. I always feel different and thus like I shouldn't even be there. There are very few people who actually make me feel comfortable. The older I get the more I am aware of differences between me and other people and it's hard for me to find like minded individuals. Most people to me seem very boring and I feel like I'd rather spend my time alone than with boring friends. I have high demands on those around me and I hardly make friends with just anyone. I feel like most of the people around me don't share my values and interests and therefor I just have nothing to talk about with them. I like the conversation to be on a certain level, but mostly I see people as shallow and unworthy of my interest in anyway. It sometimes goes to the point where people almost disgust me and I can't take their company.
I don't know what do to about this, because I long to find friends, but I am very quick to harshly judge anyone who comes near me.

So how could I be more socially open to new people? How not to judge everyone in such a negative way?
