fraid i dont have much useful advice for you rainbowzz though i agree with Sky about alternative therapies both for the anxiety and the nausea. thinking out of the box sort of stuff can sometimes help you find something that at least eases things a little.
the only other thing is that if you can manage it financially give yourself and break and dont try to work on top of all you already have going on. thats by far enough for one person to cope with already!
good luck and take care
