I Can't

I can't do it today. I just sat down at my desk at work. Anxiety is pouring over me. I sat in my car in the parking lot before coming in debating on turning around and going home. There has been so much stress at work and being misunderstood, and not backed up that it is taking a toile on me. I have never given less than 100%. My work exceeds most expectations. But the little things that are going on around me seem to be falling on my shoulders. There has been blame put on me that has absolutely nothing to do with me at all. I have been thrown under the bus and now feel like I am walking around on eggshells. I know that I work my ass off, my character and judgment at work could not be better. Somehow my judgment is being questioned. My boss says she will back me up but when it comes down to it, she doesn't. and I take the blame. I am a fucking good employee. Never in my life have I ever had any questionable actions. I am over it. I hate it here. I don't feel supported. I ma doing everything right and by the book. But I guess that doesn't matter. I feel overwhelmed and like I am drowning. It is getting harder to keep the tears back. I hate being here. I hate the feeling. I hate the people. I am ready to move on. All of that would have been perfect had I passed that damn exam! I think I am going to leave. I have been clocked in for 10 minutes and I can't handle the internal anxiety and feelings of worthlessness.
