What are you even...? I'm confused by your questions but...Hey, I'll give it a shot :
The point of taking as many advanced classes as you could handle was so you can be a competitive student. When applying to colleges they take into account the rigor of your schedule. They're looking out for you.
Sure you'll only get a bump up for 8 (I believe you meant) classes out of your 22, but you were learning at a higher level during all those classes. You're not being cut short.
The classes weren't a waste. The colleges are still seeing your classes. You have a 3.61, your friend has a 3.79. Big whoop. I'm sure you have things are your schedule that look better than theirs. You have to have some responsibility on your grades, though. They weren't awesome 100% of the time because you have only have a 4.0 weighted.
I suggest you learn for the sake of learning. Not for a silly number. If you really valued the work that you put in so far in your high school career then you would know that you're smart and that you're not at a disadvantage.
