Look take my advice with a grain of salt especially since jumping isn't my method of choice. It literally takes a lot of courage to build yourself up to jump to the point where every video I've seen of people jumping it looked like they just didn't care anymore what happens to them. And until you're at that point of not caring then it's going to be hard to get over the mental gymnastics. I tell myself that your pain has to outweigh your fears because only then can you become jaded enough of not caring what happens to you. Sure people say you can get drunk and/or take drugs to numb yourself for the attempt, but regardless of what you take or how you reason with yourself you're still going to have to channel all your suffering to attempt. If none of this makes sense then I apologize, take care if you can.
