Tired of being sick

Laura
Just been signed off for at least another week with severe sickness, I've just about had enough of it and am really low in mood. 
Baby is fine, had 12week scan yesterday and it had the hiccups, but I feel I can't enjoy it as I'm so sick all the time. I feel guilty for not being at work and not keeping the house/walking the dog. 
Any tips? I'm on meds already.
