Live in Montrose and don’t know how to make friends.

I’m turning 26 in about a month and a half, and I haven’t had a friend I can hang out with in over 3 years. It’s really getting to me. I’ve never been the type to go out alone and be able to socialize with complete strangers, and so I end up just staying in my apartment drinking the days away. I have a hard time relating to people which definitely contributes to my difficulty making friends. I live in such a lively part of Houston yet my life is the complete opposite of lively. I do go out and enjoy things alone but after a while it just doesn’t feel the same. After a while it’s just hard to continue like this. I’m not sure why I’m posting this here but I really just needed to let it out.
