I call it taking a ride on the Mood Swing. I also experience the same thing, one minute you're just fine and then POW!!! Out of nowhere comes the rage. And the explosion at whoever might be in my path. Then comes the sadness and guilt, maybe an anxiety attack to top it all off. Just know that you are not alone. It's not easy to deal with but i'm trying to remind myself that I have an illness and I'm trying to get treatment for it. I am hoping that you do the same. Remember that you must take care of yourself. The other day I made a list of all the things that make me feel good. What I now try to do is pick one of those things when I feel one of these episodes coming on. It's not easy but it works sometimes.
Keeping you in my thoughts....
