The likelihood of me going to a UC? Chances mere impossible? Is it still possible?

While i know my grades are not nearly as close as what UC wants. My GPA is 2.8, I know terrible and no matter what there's no excuses. No one but to blame myself. There are things that affected me but i guess i was not strong enough to withstand it (i been facing a lot of things and well they affected everyday life and now I'm paying for it) Now i know what i really want to pursue. I want to get into the forensics science field. I want to go to a UC that has a good program. But my grades and GPA is not good at ALL. I tried to see if funeral director was something i would pursue cause my community college offers a program. But in the end it was just not for me. I'm 19 years old. (In community college) I'm lost. I need advice. What can i do? Raise GPA? My question is What do i do? (Please do not say things that are quite obvious, i know this is my fault, i know i have a horrible gpa, i know that it's competitive, i know that right now i won't be able to go to a UC from my gpa) But i need to know if there still a chance that somehow if i work from now on very hard is there a possibility that i can go to a UC.
