I am fully freaking out about college...?

So basically if you looked at what I'm doing and getting out of college you would think i have it made..really tho as of now its the exact opposite. I am going to be a freshman at an NAIA college. I'm playing softball and basketball there and basically have a full ride. Thats the only good part. the negative part: b.c of the summer softball season just being finished for my HS i have been unable to lift according to my workout i was given by my future bball coach. so im behind there. second:one of the girls on the team will be a junior and attended a conference rival of my HS when i was a fresh/soph. I guarded her and words were exchanged, lets just say, she still holds a grudge. and finally: b.c of all of this i can't sleep. right now it is 4:15 am. and everytime i attempt to sleep tonight my mind begins to ramble and i start freaking out and crying...i just dont know how its going to work out...and i DONT want to be a failure. that is my biggest fear of all...
