Feeling hopeless....

No matter what I do or eat my numbers are always higher. I have been tracking my blood for two weeks now. Fasting number I need to be under 95 but I’m usually 100-120 in the mornings( with only drinking water at night ) then during the day I need to be 135 or lower one hour after eating and I’ve been anywhere from 115 to 160. I mainly am eating salad. Having snacks frequently as well to make sure I’m keeping myself full as I’m hungry constantly and I just feel defeated I was trying to control it with diet so I didn’t need any insulin and I’m definitely out of luck I feel they will 100% put me on it at my next visit.
