I'm 26 and lonely. I never know how to interact with people or have relationships. Am I too old to change?

Hey everyone.<br><br>I turned 26 in November, and I'm a bit of an introvert. I've always been terrible with people and stuff, and I'm not sure how to get better. I have a few people I talk to, but we only say hi and talk about the weather, etc. I just met my neighbors, and they seemed nice, so that's good. But I'm not good at connecting with people. I've been lonely my whole life.<br><br>I'm just wondering if it's possible to get better at this stuff. I feel like I'm pretty much a hermit, and I don't know how to interact with people. It feels like my social skills are that of a kid.<br><br>If it is possible to change, where do I start?<br><br>Edit: wow, I wasn't expecting so many responses right away! thank you everyone. <br><br>also, a lot of you are suggesting therapy, and that's a good idea. I had therapy for a month back in college, but I couldn't afford it any longer. I get disability, so I don't have much money.
