Please, please help.

I’ve been rejected by almost all the colleges I’ve applied to. I have decent grades, and I’m taking the hardest courses offered at my school. I’ve been rejected by UCSB, UCSD, UCLA, UCD, and Georgia Institute of Technology. I’m really depressed. My friends are all getting accepted into their colleges, and I’ve applied to 16 colleges, and already rejected by half… I really want to go to college. My stats compared to my friends: Sat - is on the same level. They have slightly higher grades, but my extracurriculars are what show what has kept me busy. I also didn’t mention the fact that I had to help suicidal people during the time I had bad grades because I didn’t want the colleges to find them and institutionalize them. If I had that in my essay, it probably would have had me in the lead. Please, if anyone can offer me advice, please do so. I feel really depressed right now.
