I have not been sleeping well the last few days and am so tired. I sit all day long so I feel like I should not be so tired. My brain feels like it is in a fog. I can't seem to think straight or remember anything. I get so frustrated with myself when someone asks me what we need or how they can help because I can't seem to think of anything or keep it straight in my head. Am I going crazy or does any one else feel like this?
