I know what you're going through-- I've got anxiety as well and had to drop out of school because I couldn't take it. I was lucky though, because they didn't get serious until I was older and already had a university degree so there were still some option.
But like you, when I dropped out the first thing I thought was 'now is the time'… but then some time passed and when I explained what was wrong to my parents, they were really understanding and helped me to relax and figure out my next step.
Can you not get help from someone? Maybe someone could give you some medicine to help with the anxiety?
I know it's hard when you're a guy because people don't really want to listen to you like they would if you were a girl… and we're less comfortable showing weakness and all that… but seriously, at least TRY to get help.
