I failed a bridge jump too since the police were a witness to it. I'm sorry for what you're going through right now and I wish there was an easier way for all of us to end our suffering.
I'm planning on using a
firearm. Not sure if that's an option for you where you live. In the US despite what people claim about how you can "just walk in and buy a gun" it's not true at all as you may have to get permits, make sure your IDs are up to date, and be questioned by the dealer (hardest part). However, you can legally purchase one although there will be some steps you have to take to make sure you can get it legally. It isn't too bad it just takes time, unfortunately. Illegally, that I can't and won't help with. If it is an option for you I could give you a bit more info.
