sitting on bathroom floor

Hi All
I'm literally sitting on my bathroom floor crying as I cannot stand the morning sickness. I keep dry heaving and nothing seems to give me relief. I have lost 2.5 pounds in one week because I cannot eat. No vomiting so far. I feel so guilty for feeling this bad when we have been trying for so long to have this baby. I am not currently working but hate being homebound for not feeling well as I usually have an active social life. 
I have talked to my doctor about this and she has recommended some medication. 
My emotions are a wreck as I am supposed to be happy about this pregnancy but all I feel is crappy.
