Im to young for this!!

Hi all just needed to vent. I was involved in an automobile accident June 5 this summer, I have been at physical therapy for a while now. I go 3 times a week, meeting with doctors all the time, and am currently not working. I am 21 years old and just found out today that I have multiple bulged and herniated discs with pinched nerves. I was rear ended leaving work and now over 2 months later no signs of progress in the future at all. Im to young, I went to school to become a police officer and now worried about my future career being in jeopardy due to someone rear ending me. I have been active in sports my whole life. I was always doing something active But am not stuck at home everyday watching tv and on FABO. I really don't know what to do anymore. Sorry for venting its just so frustrating, and depressing. I have my whole life ahead of me!!!
