Finally told my psych about my Adderall/Vyvanse abuse

I've been badly abusing adderall/vyvanse for the last 2 years after lying to a psych and getting a script. Last September it got so bad that I accidentally overdosed on sleeping pills and went into psychosis while abroad. I woke up in a hospital in Greece to my stomach being pumped. Isolation re-triggered my cravings and for the past month while quarantining I've been abusing so badly that I've thought at least once a day I was having a seizure/stroke/heart attack and have been experiencing extreme panic attacks and anxiety. This morning I finally told my psych and she's going to cut off my prescription. I'm now going through withdrawals, and I'm scared, lonely, depressed, and experiencing a lot of self-loathing. But I'm free. And I want my life back.
