I Get So Weak I Can Hardly Function. I Try

I get so weak I can hardly function. I try to sleep and wake in a short period of time maybe 15 minutes. I feel like there are spider webs on my face and there is nothing there . Seems like I feel better when I am outside , not so weak. If I rest for a short time , most times I feel better. I am not over exerting myself , maybe just some painting around the kitchen and I feel the symptoms coming on.
