Finding it hard to be happy.

So I have been trying so hard to get pregnant. We finally did it and I am 11 weeks today! I want this child so badly! Now that I have said that.... I have been so sick that I have lost the excitement and joy that I originally felt at the very beginning. I am over weight and have a friend who is one day further along than I am. She is barely sick and already showing...I am extremely sick and probably won't show for another two months. It all just adds to my loss of excitement for this rainbow baby. Is any one else dealing with this? I really could use the support of you wonderful and beautiful ladies!
