Tired and exhausted

Am I the only one feeling this way. I am tired and exhausted. I am crying now, somehow I can’t stop crying. I am 32 weeks pregnant and have gestational diabetes. I need to go to office and my body feel exhausted everyday. Today my diabetes nurse called me regarding my readings. She told me I must reduce my food intake. I told her there is an 8 hour gap between my meals so I need extra snacks, all I ate in that time window was few cashew nuts , an apple and 2 thin biscuits. She flatly said I can just eat an apple and that’s it. She talked to me as if I am not not taking care of my baby. It was really sad for me. I am eating the same foods everyday as there are only few things that controls my sugar level. I am hungry every evening after work and travel still I don’t eat anything extra so my sugar levels will be under control. Also go for walks as my doctor said so that my sugar levels can be controlled. I feel tired everyday. After all this to be scolded and listen to her saying that I am eating too much is hard for me. Please don’t judge me, I just wanted to talk to someone, because I can’t stop crying. I believe there will be more people who experience worse here and be able to talk to me.
