Computer issues: posting via phone

I'm using a talk to text application in order to post this because on my phone it is very difficult to type. And I am too exhausted to be able to even sit at a computer and type right now, my eyes aren't even open.
I am utterly and completely exhausted. When I try to stand up and walk very shaky and I I feel like I'm going to fall over like my knees will give way and Iegs will buckle. someone asked me today if I think it is my depression or the fibro that is making me so tired. And I questioned that myself because depression and exhaustion go hand in hand. But I want to get up and I want to do things around the house and I want to look for work. I think if it was a depression making me sleepy and wanting me and bad that I wouldn't want to do anything else. I've been there before.
