Hey dude. 21 y/o as well. The way you described yourself applies to both of us.

I don't live with my parents, but unemployed and out of school (dropped out two years ago), haven't really done fuck-all in those two years. I spend 90% of my day in my comfy reclining chair in front of my computer. Generally unclean, don't shower much, will skip meals just because I don't want to make food, I eat a lot of subway cause it's easy and filling, and never really go out much. My room is a fucking mess and everything is just sitting in big piles.

But there's one key difference between us, I think: You've hit a dead end. By living with your parents you've closed yourself out from the outside world, which is sort of okay except you don't seem to have a great "inside" world either. Your life is a closed system, with nothing/nobody coming in and nothing/nobody going out.

Right now your life is one bubble of air in a great big ocean dude, you need to break it and get yourself out there. Yeah things will be disorganized and less comfortable out there, but let's be serious you CAN'T keep living like this forever. You're not growing, you're just preserving yourself as your life stands still.

I can say this stuff with confidence because my life is in the same state. The only key difference between us is that I live in a house with a bunch of students in a university town. I have a lot chances for people and opportunities coming in and out of my life, so I see glimpses of the "outside world" so to speak. I can look at my own boring, comfortable, familiar life of mediocrity and compare it to (what seems like) the vibrant and dynamic lives of others.

That being said... their lives do seem like a pain in the ass. I lack the motivation to study or get ready every morning. I'm not sure how they tolerate it, but hopefully I can learn.

Send me a message if you want to talk, maybe we can slap some motivation into each other :p
