Time is your cure.
Suicide is never the answer. I'm sure if you looked at some suicide videos on the net, you would think twice about doing it. At least, that is what happened to me.
Talking about it and seeing it actually happen are two completely different stories. Death in general is reality, and it's scary.
I tried suicide one time. I took 80 coricidin at one time. What happened that night? I hurt my family, I hurt myself, and I almost died. The people who loved me would have been devastated if that had happened. Think about your loved ones.
I'll second that. I tried it once too, I have to say that it must have been half-hearted because luckily enough I didn't succeed. A litre of vodka, coke and 120 diazepam. I feel ashamed to say it was a cry for help because i didn't think that was my intention at the time, but before I fell unconcious, I alerted someone so as many times as I had considered suicide in the past I obviously had a second thought. I was in a bad place at the time and I still don't know what made me chuck all those pills down my throat.
After being Bluelighted to hospital where the amazing people there saved my life, which I can't thank enough for their care from my self inflicted behaviour, I know it was not the answer. I came away unscathed, but my family went through hell while I was quite oblivious to what was going on. It is not the answer and the fact that you are asking how much you need to succeed with an O.D sounds to me that you don't really want things to end that way.
Don't feel ashamed to ask for support. Life can be full of shit, I know as well as many others do how hard things can get.
I also know that with the shit I still have going on that I will not do it again. I'm not going out that way. Neither am I going to let the addictions I have take it either. I'm in a dangerous place with them and i am struggling I will admit. But my life is not done yet. So one way or another I'll have to beat them before they beat me.
Your life is a blessing, don't waste it that way. You don't know what goodness can be waiting just round the corner, and if you end it you will never know. You don't know how important that it may be that you stay alive, you may be the one that will save a life one day, which won't happen if you aren't around to do it. Someone elses life may depend on yours!
All the love to you!
