Cobra use to have a lot... A LOT of anger towards his wife, when he first started posting here. He did as you, tried to eat a lot of crap sandwiches for a lot of years to keep the peace. Im not sure why he is baiting you like that, but stick around. you cant do it on your own.
I dont expect you to 'control' your new chemical cocktail, anymore then I expect a woman to control her emotions on those special days of the month, but you need to be aware of it and take care of your health even if that means pestering your Dr.
You dont have to let others provoke you to showing it though. Save it for exercise and paper. Feel free to wax your irritation at me..:) better yet, Start getting some regular heavy duty exercise. Buy a heavy bag and beat and sweat your frustrations out on the bag, or something similar.
You cannot allow anger and uncontrolled spitefullness to be a part of your interactions with your W, if you want to work on things. You can be severely displeased, and show emotional forcefullness.
You swung the pendulum too far one way, and now your at the other end. Hold onto yourself and get centered. You can do it.
