Gestational Diabetes

Anyone experienced GD during pregnancy? How do you brave through your insulin shots and how many times a day will you have to do it? Will it leave any bruise? Doctor kept pushing me for insulin but I really do not want to. They said fine but in future I have to mentally prepare myself as highly likely I will have to consider them. I have concerns in many areas, cost wise, pain wise and commitment wise. Can you share your experiences?
