When you have the massive flu you have a hard time functioning. You are sick to your stomach, pain, vomiting, fever, diarrhea, and so on.
This is how depression feels to me. Sick to my stomach, aches and pains, no desire to move or get up or eat.
Depression can be paralyzing. That's what it's been for me for about a week now. I had no desire to clean, cook, or do much else for that matter. I was numb and just existed. Not a good place to be.
This morning I feel like the "Flu" is gone. I'm better. Still weak, and exhausted, but able to get up and do some things that I normally do. Hopefully another day or two and I'll be back to myself, happy and doing well.
