Stressed!?!?GD

I am 32 weeks and have Gestational Diabetes and recently was given insulin just for my fasting numbers so I take it at night, The rest of my numbers are great but my fasting numbers are still high I don’t know what else to do, why can’t my fasting numbers just go down!! This is frustrating me, any tips? I also do have appointment on Monday but any tips to help lower it till then would be appreciated
