Hi crook,
I'm a 45-yr old mother of 2 daughters. I suffer with treatment-resistant depression as well...so I've been "in-patient" a few times. I've met a few other people who went in for ECT and had a variety of outcomes. Most have complained of major headaches the day after treatment. One didn't. But, she was in the minority. Hopefully, you are too.
You're welcome to message me, if you like. Take care!
