What do I do?

Okay so, I'm a teenager applying to colleges in this cycle. I have a 2.7 unweighted but i take college classes and IB. I play sports, do the arts and volunteer. My SAT is a 1210. My current problem is I'm drowning. I am smart, and if I had applied myself at any point, (and did) I would excel. My transcript is straight As first semester, and then near failing grades second semester. During each year unfortunately for me crazy things kept happening second semester. Crazy shit like Being outed and essentially shunned by my family, friends dying, randomly being beaten for months straight, etc. I live a weird life. All that aside, I have hopes and dreams for where i want to go to college, I wanted to go to an ivy, it was always the goal, and you can see that cause each semester I started fresh and did a great job in the beginning. Then life came along, and in the face of all of that, it was really hard to give a shit cause yk, I didn't expect to live this long. Now onto the current dilemma. I have so much potential and huge dreams, and will still be applying to those ivies but I am scared shitless, and I have no idea what I'm doing cause I have a 1% chance of getting into all those schools, and applying to only reach schools is an atrocious idea. Does anyone know any good schools I can apply to? Or what I can do. I want to be a surgeon, or just work as a doctor, but all in pediatrics. I'm kind of stuck at the moment because I'm deathly afraid of failing. I think if I apply and I fail, I have no idea what I'll do. I don't want to end up in a dead- end job living with only regrets, does anyone have any thoughts? Advice? I just need some kind of plan or vision. I want to EMT through school but its not the end goal.
