I feel like I'm going to be sick

I'm the oldest sibling in my house so I really have no idea what I'm doing and i'm so stressed. I only applied early to Tulane (got deferred today), and I applied to Wake Forest before their merit scholarship deadline, and to UT Austin on November 6th. I submitted the app EA but realized I never sent my SAT score so it's not considered EA :(. UT is my dream school since my parents went there and I was born in Austin/have family there, however I am out of state. I'm applying as a biology major which isn't one of their more competitive majors but it's still a bit of a reach for me. (1510 SAT 740 EBRW 770 math, 4.62/5 W 3.86/4 UW, rank 55/403 at a competitive public high school, average EC's, good essays, 5's on AP Lang, World History, and Gov and 3 on Physics 1, NMSQT commend student).

I'm super stressed that I don't have a college I know I can go to yet. University of Maryland-College Park is supposed to be my safety but my dumb ass hasn't applied yet. I'm submitting my app tmrw but I didn't realize how important it was for my to apply early so now i'm freaking out. I'm still also applying to Lehigh, GWU, American, and Santa Clara as regular decision but I'm so scared I'm not going to get in anywhere I like and end up going to UMBC. I legitimately am so stressed I feel like I'm going to throw up. Please help :(
