I've been in this place ..and that's when I just hold on to everything I know and believe about my Lord. We are told in his word to pray without ceasing. So pray in good times and pray even harder in bad times.
I'm not big in this type of things, but this is def something that any college student should take into consideration. Worrying causes you to lose focus and not concentrate on what is important so just read this and trust that it will all work out.
