How should I go about making new friends?

I've been feeling quite lonely and unwanted recently and I'd just like someone to talk to. I've always found it easier to text girls but making friends with them is hard since I can be a bit weird socially in person. I've never really made friends with people outside of the guys I went to school with and I'm in the middle of holidays between the end of school and the beginning of college.

I'd like some advice on how to and where it is okay to approach people and make new friends I can talk to everyday.
