I don't know if I'm manic or depressed but I'm losing all of my energy and my mind trying to stabilize myself.

I've been bouncing around in a constant state of what I thought was mania for about a month or so, but all I do is cry and spend time thinking of reasons to disappear. it's getting worse and all of my coping skills that used to help me, aren't doing anything. My paranoia has been getting worse and worse lately to the point of being too afraid to shower when I'm home alone because I'm POSITIVE someone is in my house and if I'm not on watch, they'll get me. I've been so mean and stressed lately. I can snap in a split second. I went from not sleeping at all a few weeks back to now where getting out of bed is the biggest struggle in the world. always tired, always cranky, always upset.
