I need help some advice from people=(?

My girlfriend of 4 years left me for bestfriend...I'm really thinking about killing myself....I'm a laughing stock at my high school because people knew about them messing around behind my back, my parents are getting a divorce, and I really don't think I will be able to go to the college(LSU) i want to go to in the fall because of money issues...i'm very depressed and just feel like saying **** it.
