Jo, I know that your dd loves you, getting a bit grouchy once in a while won't change the love for you. I also know how tough it is to lose a baby, W had a tubal pregnancy between D15 and S12. This was about 14 yrs ago and it still has left a hole in my heart. W had a rough time afterwards also.
Remember your goals and what you have worked so hard for. You have come to far to give up now. Jo don't let daily stress or past events to dictate your future. Remember you can vent all your feelings on this bb, try not to hold anything in. When I don't really vent on the bb how bad I really feel I end up snapping at someone in my family. I guess venting just lets me blow off a little steam at a time so I don't blow my lid.
