Please help. I am serious and need your advice. Thank you?

I am 23 and have attempted suicide a dozen times sicne January by overdosing on my meds. I know the police have been here about a dozen times, they're sick and tired of it. I'm sick and tired of it, we're all sick and tired of it. I have had it with my life. I want to overdose on my meds tomorrow when I'll be home alone and not have the police or ambulance techs or hospital judge me. How can I successfully get it done. I take all the pills I have and I just can't get it done right. I am losing it. I do not want to go on and I don't want to go to the hospital and be judged. So what can I do. I am serious
