Highs and Lows

Hi, I am really confused, because I don't know what I'm feeling or whats going on with me lately. I recently (within last month) came out with an abuse issue, and it was something happened ages ago.

I really don't know how else to describe my emotions besides that I have highs and lows, like i've never had before. Sometimes I'll feel pretty good and have this "understanding" and peace and then I always "crash" I don't know a better word to describe it, I just hit such a low, where I can't even think back to the frame of mind that I had during my "high" I just get really frustrated, angry, and hopeless.

Other than that, I also can't cry over anything, I'm just numb and this is not normal for me. I can't eat and sleep normally either. It is like I have a brick wall that won't allow me to cry or feel sadness. Just frustration and anger.

This is all a very scary feeling like I'll never "feel" normally ever again. I feel disconnected like a robot, functioning (sort of) but also so completely unmotivated...yet not completing tasks really causes great anxiety, so I do care, I just can't bring myself to do it.... such opposites.... I don't understand
