I cant make friends.

I'm sure there is tons of posts like this. I (25F) don't really have friends. I don't understand how to make friends in the first place. I don't like socializing at all and I get easily scared, nervous or shy when talking to people I do not know. I've had friends before, but they either ditched me or forgot about me and moved on. But I will admit I feel very confused that people around me has had long lasting friendships. Maybe its because no friends have ever last that I feel like its so unimportant. Both my brothers still have friends from high-school. I just cant find people with interest like me and maybe that is another reason why. I just want to give up at this point. I don't feel like friendship is important at all and I don't know why my family is trying so hard for me to 'get out there' and make friends. I like my life how it is, playing games, reading books, writing and working. I have time for stuff and i feel like having friends would make me not have time to do what I love. I get social interactions once a week with my co worker and I think that is enough and all I can mentally take since after they leave and im alone at work I feel less scared doing my own thing since im so scared ill say something wrong or do something wrong. I hate going to company get together and tend to skip and not show up. I don't like going to a gathering with so many people and have so much anxiety so I dont go, typically during this time im at home or waiting at where I work for the people to come. So even when I am given time to hang out with people I don't do it. I don't know. Honestly I feel like my social communication skill is broken and I am just never going to make friends and i feel like, that's fine. I'm always overwhelmed and anxious around people anyway. Maybe i need therapy, but I don't really feel like not having friends is a reason to go and spend so much money.
