I went through this, I had a bit of a crisis at your age. I had a good job, I had an apartment, I worked during the week, I ran errands during the weekend, I never met many people, particularly women, and I was bad with women when I did meet them.
It was a long journey for me but I found my path. I did it after an incredibly low point in my life: I starting dating a girl who liked me for months, maybe years. I finally just gave in and started dating her, it wasn't like I had any other options, I was young and suppose to date someone, right? After 6 weeks she dumped me. I had a crisis - how could I be so shitty that someone who crushed on me for a year couldn't stick around for 6 weeks once she got to know me more intimately.
From that low point I actually sat down and decided who I wanted to be and how I could get there. I wanted to be self-employed, I wanted to work remotely (I was already in software) whenever I wanted, I wanted to make good money, I wanted a super cool and super hot gf that I could be completely honest and vulnerable around and she would love me as I was, I wanted cool friends, I wanted to be in great physical health and shape, I wanted cool hobbies. So I actually set goals and I made plans and timelines and steps to achieve them. If you can believe it I read a lot of self-help books and read books on goal setting and got to work. I read books on sex and seduction, on being a man in modern society, on fitness and diet, on building a business and on countless books to become an expert in my field.
Anyway, fast forward 6 years and I'm pretty much living my dream. The more I knew what I wanted the more opportunities to get there fell in my lap. I waver and falter now and again, I'm not always as disciplined as I'd like, but sometimes I think back to where I was 1, 2, 5 years ago and I can't believe how far I've come.
You are incredibly young. The world is your oyster. You can basically achieve, create, become whoever you want. My advice to you is take this low point as motivation and start figuring out what you want and how you can get it. I think getting dumped by that girl was probably the best thing that ever happened to me.
