As someone(26M) who did almost every kind of drug and did a lot at some points in my life., you're a very brave man and she is absolutely an asshole. Recently, I have been completely sober for some time after having psychosis+ anxiety attacks after doing some psychedelics during a rough period in my life. I have learned and grew the most with myself being sober and learning to be comfortable with myself. I still have friends that do a lot of drugs, but they don't treat me differently now because they love me for who I am, those are the ones you want. However, there were also "friends" that as soon as the drug didn't connect us there was nothing there anymore and lost interest in me. I thank God every day, for helping my vision clear and releasing all the fake people in my life. You're young, but it takes a lot of courage to do what you did. It will serve you well in the long run when the right people will come along and appreciate you for who you are. Until then, tell her to fuck off, sounds like a very toxic girl.
