UC reject

Man idk what to do anymore. I got rejected from like all the UCs except riverside and merced. I understand they’re good school but damn bro. To be fair my grades weren’t that spectacular and I applied for a major that requires a great application (biomed). But also my classmate got accepted with an undeclared major that she didn’t enroll for…Now I have to figure out what to do in community college and I’m honestly so embarrassed.
