Gestational Diabetic

I am 33week preg, dr wants to start insulin every night as my pre meal abit high. Target supposely 5.5, mine abit high like 5.7. I refuse to start cos i can't jab myself. I don mind people jab me take my blood or operate but not ME INJECTING MYSELF. Yah the needle is short and tiny but so what my hand can't inject myself. Anyone got GDM please share with me about your experient. I will find a way to jab if my blood sugar is around 6.0. I follow their diet and DR say my baby is small this GDM is causing me sad and stress???
