I know what you mean. I've been told things like that before, almost word for word but for an entirely different reason, when it's something my illness is causing that can't really be controlled by me.
Damned autocorrect. Makes me look like an idiot.
I have the same issues. now I know I'm not alone. If you can talk to your partner about your feelings maybe you'll both come to a workable understanding.
Unfortunately talking to my Wife is a game of minds and because of some of the hurtful ways she has dealt with me I have no faith in confiding in her. My main issue is the way she told me to grow up and be a man when I got weepy one time. I had no control over being weepy because it comes on for no real reason. Her words went right to my core and now I don't trust her with any of my feelings.
If you can open up to your partner, you ate one step ahead of me, that's for sure. If you can, I'd be interested in knowing how it works out.
Usually its easier to determine if you can figure out when you cycle. I cycle pretty rapidly and its easier for me to tell when im going to get grumpy because ive had time to study my habits.
