You say all sorts of things when you are drunk, so I wouldn't worry too much about it. You know that you are happy with your life and didn't want to kill yourself. I know that I've gotten the urge to do stupid things while drunk before, like jumping off places that are too high and it is not so that I can hurt myself, but rather because you tend to feel invincible when drunk, so it just sounds like fun.
You sure don't sound suicidal to me
I hope you are able to work things out with your boyfriend. It's traumatic to see someone you care about get hurt badly and he probably feels partially responsible. Hopefully he just needs some time to process things now that the stress of you being in serious danger has subsided.
