Yes but your missing the social aspect of skool. Social interaction and learn things from behaviour of other youngsters and the interaction with them.

U only get one chance to get skilled in social interaction in life. To polish your charisma, get feedback, get friends, fix girls etc.

I don't like the way most teenagers act, having to deal with them everyday would turn me into an asshole.

I understand that. I agree. But such is life. I hope ur isolation strategy works for the best.

I don't have an isolation strategy, I just don't want to be social with most teenagers.

I like being social with young adults but they don't like hanging out with minors.

5.5lb isnt so much that you really need to worry about it you've been eating badly, so your body is taking what it needs from other sources, or maybe your metabolism has sped up to deal with the crap you've been eating. - but it could all be in your head, caused by excessive alchol consumption
