Well, the perspective that your worries didn't seem like reality while intoxicated might reveal that they aren't as serious as you think. Doing drugs isn't good. I didn't think I'd have to say that, but I guess I do. Maybe it's more of a sign that you and a doctor could find a medication that could help you.
It takes a while to get a life together after drugs. The body has to adjust, including the emotional controls. The brain has to learn to navigate and regulate itself. Getting away from intoxication also means learning to face what was being hidden by the drugs. It's always a pain, but it can be worth it.
I mean, I guess this is a place that accepts suicide, so it's not like people wouldn't accept the individual right to do what they want. Still, if you're going to live, it only makes sense to try and live a good life and a healthy life. It's not just one day at a time. It's one moment at a time.
I hope you find peace.
