I Feel Like a Failure Sometimes

I know I am a failure... I am in my senior year and I failed my geometry class twice. it was the only class I failed, I was supposed to graduate in December and I do online school. I know I am a failure all I have been doing is crying and taking pills, I am so extremely unhappy I do not know what to do with myself. I have been telling all my old friends I am graduating and that is not happening, I am so upset with my life. I had just gotten into a car accident and know I failed my senior year.

Apart of me wants to get it over with and take my life because I do not think I should be in this must pain. I feel like if I ended it, it will all be over. I just want to go to college and be happy, thats all I ever wanted in my life and now that is being taken away. I am a failure and I do not know what to do with myself, I want this feeling too stop I feel like I will never ever amount to anything good only negative.
