You are young, you did a huge mistake (but you stopped), and you have probably lost a friend.

Now…I’m sorry but you’ll have to deal with it. It’s okay. I just hope it will teach you to not try this again.

The good thing is that you seem to regret it, so it means that you somewhat understand the issue.

You have no idea how many did that kind of mistakes. Just learn from it and be better.

I advise you to leave her alone, unless she wants to talk with you, and talk to someone (psychologist for example).

You do not deserve to die for this.
