Overdose? help please

Hi I'm 15 and I always wanted somebody to help theough what I go through but it seems like there's nobody in my life at all and I'm scared to talk about it to an adult because I don't want it to be a big deal to others until it gets to the point that its my family's fault but umm...I tried overdosing three times past last month I felt dizziness and I was very cold throught my high school day ..I just want my life to be over completely but nothing works I tried killing my self million of times when I was younger ...but the point is what I want here is if I kept trying to overdose will something happen? Will I end up in the hospital? Or is there enough time to even rush me to the hospital?? How long I'm I going to stay there in the bed?? Please take your time answering this qustions?

I am sorry that nobody seems to be there to help. You can call 1-800-SUICIDE. Try to talk about your problems. Also, is there a teacher or a school counselor that you feel you can trust?
