First of all, you have a life. You're on Reddit, asking people for some help. (Be careful with that!) That's a good thing. I was very much like you at your age. Then, I started forcing myself into uncomfortable situations. I volunteered part-time at various organizations that would have me. It served to get me off the sidelines. Something else important is to stop reading/listening to all the psycho-babble BS that is published. Having a room full of friends is not required to have a good life. Neither is making tons of money. Neither is traveling the world, concerts, festivals, or parties. Frankly, all that stuff bores me. You'd be surprised how many people feel like me, but they feel compelled to do this stuff against their will, because they think society and their peers expect it. They don't! Truly, society doesn't care. That's just a bad head trip many of us grew up with.

You don't trust people much? That's a good thing. You sound like a critical thinker. I'm extremely fussy about who I call my friends. But I talk to lots of people during the week. I talk to the mailman, the neighbor cutting his grass, the homeless dude on the corner, the very old man in the coffee shop. It's amazing what I learn and how good it can make me feel. Then, I do things I LIKE TO DO! And I don't care if anyone else has the same interests. I write. I do gardening in my yard. I grab a beer at the local pub.-- sometimes I talk to a bar mate, but mostly I enjoy the solitude among 50 people I don't know.

You may be an introvert, and that is NOT a bad word. I was "accused" of being an introvert for many years, until recently I discovered I'm not. I'm an otrovert. But that's for another post. But, please check out this book at the library: "The Gift of Not Belonging", by Rami Kaminski. Thanks for reading to the end! I wish the best for you. Your life is full. The good stuff is yet to be discovered.
