With my luck.

I’ve been researching different methods of committing suicide and as I’m reading through all of these, tempted as hell, I just can’t help but think that with my shitty luck, I won’t even be able to successfully commit suicide because something is going to go wrong and I’m just going end up with permanent brain damage or something. Does anyone else feel this way? I’ve been depressed on and off since I was about 14. I’m 21 now and have decided on using an exit bag, but have read about so many failed attempts with one on this forum and now I don’t know what to do because I just feel like I’m going to be back on the forum crying about how it failed and be even more miserable than I was before.
