That would be my suggestion too.
Look, if you really wanna try heroin, I have no doubt you'll find a way to get your chance sooner or later, assuming heroin exists in your area.
But I can't in good conscience help you do it. All I can say is that in my experience, either you'll like heroin or you won't. If you don't, it probably won't be an experience that was all that worth having.
If you do, there's no going back. I mean I dunno if you've tried other opioids, but once you do, it's not an experience you get to forget. And if you're one of the types of people predisposed to opioid or heroin addiction, it can easily turn out to be the first step on a path that can fuck up your life to a breathtaking extent.
Good luck, I wish you well, but unless you're literally on the edge of suicide already, I don't see any chance of heroin being a positive thing in your life.
