I think I'm in the same range age as you, and I get it. But I'd never wanna leave my life right now. None of my family share my (fish) interest, but they still respect it and compliment my tanks all the time. If it's just the hobby that you're dealing with, man, you're lucky have big tanks and stuff. I only have a 10, but I'd rather have that than loose my family. And, where are you gonna get your money for? Your room mate isn't gonna give you your allowance, or supply you your food. It's much worse. Plus, if you dropped out, how are you gonna go get a job and support yourself and your family when you're older
Think about it. I've thought about leaving before, but I thought staying would have been a better choice. Dude, I'm you're age and understand it.
