I would never try it, because you're more likely to repent it once you jump, and then you will experience an adrenaline rush and your body also releases endorphins and serotonin, which are known to make you feel happier, you gonna regret leaving life, so you gonna spend the last moments of your life regretting killing yourself.
I was on the edge of the bridge twice. and I practiced falling of my bed lol and from 2 meter height it was both scary and hilarious, I don't know how to explain it, but you can try it ( fall off the bed or a decent height not the bridge lol)
