Gestational Diabetes...

So my doctor just told me I have to see an endocrinologist and take insulin shots on top of checking my blood sugar 4 times a day.. I'm so stressed out and my anxiety is so high because I have a bad fear of needles. It took me forever to prick myself because I couldn't stop shaking. Any tips on how to deal with having to give myself shots? And any tips on keeping a good diet?
