Who can relate?

I know pretty much everyone can relate to having morning sickness. I'm in my 10th week and I guess it's peaking for me. The thing is I feel completely useless. The headaches, nausea, dizziness, weakness and fatigue. It's been taking over my life. It makes me feel kind of depressed because I feel like all I do is lay around and I hate feeling unproductive. Does anyone else feel like they aren't functioning?
