So tired of trying to fix this

I am fighting for my life, literally. And no one would know it unless I told them. What sucks is that it isnt even my PMDD time, it's because I'm adjusting medication BECAUSE of the PMDD. I hate having a chronic disorder. I know no one loves having one but this is just so debilating and exhausting having your life revolve around this. I'm in so much mental pain right now. Just a week ago I felt so good. I love my life. So it's so distressing feeling this way. I took off work for the past two days and my mental state was so bad that I dragged myself into work today because I'm scared to be alone. Huge mistake. I still can't function. It's only been two hours out of a 12 hour shift and I had already broken down crying. I cant be home alone again though. My husband works and my daughter goes to daycare. I could always go get my daughter but I dont even know if I could entertain her all day. I feel so trapped in side of myself but at the same time not here. I love my life but I hate this.
