He slipped because in my ECT stupper i gave him my pin # to go with my bank card i'd already given him and he was fine until he ran into an old drug buddy of his.
Shutterbug, he slipped because he chose to remove the money from your account, go to his dealer, buy drugs with your money and then ingest the drugs. If you notice, you were not part of any of those decisions. It is NOT your fault. As we say over in the family and friends forums "You did not cause it, you cannot control it, and you can't cure it."
As for the forgetfulness, I knew a couple people who had ECT and they were told that every time they typed in a password, made an appointment or so on, write it on a sticky note and place it where you will see it without having to look for it. Do the same for your appointments. One lady put her calendar over her underwear drawer so she'd see it every morning! Whatever works, use it.
Take care, and please be careful.
