Lucky 
I dropped out of high school when I was really young.. I wish I could get a job but it's so hard where I live. I don't know if a GED will be hard.
It's hard to make friends now that everyones on their phones, maybe go outside to community places, public transport for example, strike up conversations if you see the same people over and over again, and if they ever invite you somewhere, go there.
You could go to a coffee shop and hang out with old people, or to a bar which is a bit less exciting, and keep going there to have fun. I've always been frightened of the gym despite being around 60kg
You could always volunteer, which country are you from? You could look at apartment posters, or whatever poster is there in the community.
The phone kind of made everyone a NEET in a way, and university is probably the last place to make friends officially. You could check out sites like Tagmap(even if it is dead) with weird anons. Try going to conventions, anything. I've felt that the feeling of being a NEET leaves you once you regularly develop a habit of studying. Good luck hikarin!
