I'm a junior and need to sleep a lot to function properly.

I go out with my friends every friday (sat is off) and it always fucks my sleeping schedule, to the point of not waking up to school a lot.

Thinking of not going out anymore because there is no common time that we all can go out, my friends are uncompromising so this means that we won't be friends anymore but Im going to see them every day at school and they are going to resent me(we're 4 and one kinda does anyways) . and I won't have any close friends for 2 years.

This is pretty complex and there are more details but in conclusion I'm going to make a tough decision and need help finalizing it.
