Every semester has just gotten better since serving. Yes it's been daunting, but I've had some of the coolest life experiences since then. You've got so many awesome times ahead!!
I've been stressed over all the stuff mentioned in the OP and one night was praying and mostly jokingly said "can't I just skip to May?" and the clear answer that came to me was "You'd miss out on a lot of crucial and pretty amazing experiences if I let you do that".
Your best is yet to come!
