Friendless and approaching 30

I don't know how to initiate or make friends and I struggle to maintain friendship. I also feel like a lot of people tend to gossip which I don't really understand or like (it makes me feel uncomfortable), I would rather talk about other things that are interesting or inspiring. I struggle with depression and don't have many interests bc of it so it's hard to go out and find shared hobbies - my main hobby is art which is a pretty solo hobby. Next month is my 30th birthday and I think I will spend it alone crying like most birthdays have been before. People say that I'll find my tribe but I'm losing hope and I know I'm the problem. I wish I had people to celebrate with, someone to talk with, share emotions and go out etc. Idk the point of this post, ig does anyone else around this age feel the same? Does anyone have any advice? Does it get easier being alone?
