downandlonely, thank you for your support. Your words help me feel I'm not standing here by myself.
whatever2013, what an interesting study. We definitely fit that pattern.
sarahsweets, she's not working with any other ECT patients as far as I know. She's not an expert on ECT. I am working part-time though, so she may feel that if I'm doing that, then why not full time. (I work 12 hours per week with zero social interaction some days. I basically sit and wait for the phone to ring. Not much stress. :-) ) The letter is a good idea. I think it's time I write her.
Wander, you've got a good idea in that I should ask her how to push myself or judge my readiness.
BirdDancer, thank you for the affirmation. To clarify, I'm working Tuesday, Wednesday, Thursday, so I get ECT on Friday, have all weekend to recuperate, and though a little loopy on that Tuesday, I manage to hold things together. I think talking about "working" with her I've given her the impression that I'm tougher than I am.

Thank you, all of you, for the help in this. It's scary to confront her because she's such a wonderful aide and teacher in coping. I need to do it though because this has impacted our relationship. I'll let you know how it goes.
