<human>: Condense the text into a few key points

Alright so like I said I'm a senior in high school and I'm kinda having a panic attack. Triggered by my dad and his girlfriend. I have a college visit at the university of wisconsin: madison saturday. Exciting. But since I found out about this visit people have been telling me how hard it is to get into and they completely crushed any hope I had of getting in. I haven't taken my ACT yet and had planned on doing it on the 8th. I'm registered and everything. Just the other day I realized that the annual tradition of performing with Tuba Christmas was also happening on the 8th. So without talking to anyone I changed my test date to February. This caused my dad and his girlfriend to flip. "by February it'll be too late to get into any schools"  I'm not sure how all that works but I can't imagine it being like they are saying. 
I'm looking to go to school for environmental sciences and forestry. I haven't done much research on schools around my area either. I feel completely unprepared. 

My reason behind posting this is I just need some reassurance that I'm not a fuck up and any help or tips would be greatly appreciated.
