When will I feel better?!?!?

I am 10 weeks with twins and I am so nauseous 24/7 I don't even feel human anymore. I have been taking medication which helps w the vomiting but doesnt really do anything for the sick feeling, plus I am extremely fatigued, and I get terrible headaches. I am barely able to care for my 2 & 5 year old and my relationship with my husband is suffering because I don't want to be touched... At all! I can't even prepare meals without getting super sick, my poor family misses home cooked meals. 
I keep reading different stories concerning morning sickness and twins... A lot of women say it went away at 16 weeks but would randomly come back every now and then. And the other half say they were sick the entire time! 
Please tell me your experience. I'm praying for light at the end of the tunnel.
