Hang in there, Moose! Your nonbf is using your stress to his advantage this week, and that's down right mean.
If it were me, I'd cut communication off with a simple goodbye email, then refuse to take any further emails, voice mails, texts, etc. It would be pretty hard to delete that stuff without reading it, but the final break has to come
sometime. Maybe when I was doing better, I might talk to him, but certainly not while he was using my illness to be more mean to me... But that's just if it were me. I've had to do it before, with a friend that had become toxic to me. It was pretty d*** hard, but I did survive.
The celexa make take a week or so to build up in your system to a therapeutic level. Most ad's don't work immediately.
Hugs,
Buggs
