Just turned 26, have no friends, nothing to do and feeling lonely. What next?

I’m a guy, I’m feeling lonely and I don’t know what to do. It’s been like this for a while. <br><br>I’m 26, turning 27 next week. I live alone. I have a good job, I don’t have financial issues, I’m not particularly introverted but I also don’t get out much. I have some acquintances but no real friends to hang out with and I don’t know how to change that. I got a dog a year ago and I love it, but I need to get out more. <br><br>I have nothing to do and no one to do it with. Actually I tend to get annoyed when people try to make friends with me. I get annoyed at people who try to hang out with me too. I’m not even active online. I’m not socially inept, I can easily get along with people if I wanted to but I just don’t want to. <br><br>I get worried about my future, I’m worried about staying lonely, not finding someone, not having children, turning 50 alone, retiring alone… I don’t know how I got here. I don’t want to be alone. I want to change but I don’t know how. Actually I know how: go out more, talk to people, join clubs, do hobbies etc… I just don’t want to do it.<br><br>I’ve been like this for years now and it’s getting worse. Maybe it’s time for therapy? But therapy doesn’t help everyone and I’m worried I’m going to waste my time and money. <br><br>I want to change, I want to be social, I want to be happy. But I’ve been like this for so long that I don’t even know what would make me happy. Is it being social? But I don’t want to be social. I don’t know. I don’t know what to do. <br><br>Should I invest in therapy? Or just go out more and make an effort to be social and meet people? I’m already active and I have a dog, so it’s not like I’m depressed or anything. I just need to meet people. But how?
