I know it probably feels like a backwards step, but actually love I think this is a huge positive for yourself. I assume you are going to stick with a given dosage of preg for a while? Helping out Pen's dad sounds like you'll be relieving a hugs amount of stress for her too, you get to help him too so that's a win/win situation...
I think it's a really sensible decision, but one I also know wasn't an easy one to make. Well done lovely for doing what your mind and body needs now.
