Hi Paula, Welcome. It does come as a shock doesn't it, but the good thing is, Diabetes is a condition that can be managed well. Another good thing is you sought us out.
Listen you don't have to live on salads , unless of course you reallllly like them.
As has already been said, its carbohydrates our bodies can't handle too well.
Read the food labels on the back of the packs, completely
ignore the , of which are sugars, sugar is just another carb, instead look at carbohydrates and you can work out , if it's worth it and or the carbs for the portion size you are going to have.
Mark in post 2 has already give a list of things to cut down/out. So I won't repeat them but, many of us have found some good substitutes. If you have one nearby, Many here have Lidl protein rolls , Bergen bread, nimble.
We often have to be careful with fruit, berries are often tolerated better, grapes are little sugar bombs. Fruit juice is packed full of sugar
Avoid things that say suitable for diabetics ( I believe that's illegal now but their still might be some knocking around) I don't do low fat , many here don't either as it's often more carbs than the ordinary version.
If you eat meat, it's perfectly fine for us, as are high meat content sausages and burgers
Eggs, cheese , fish, veg that grows above ground , some nuts are low carb too , I love walnuts, butter, cream to name but a few are actually good for us
Have I got your taste buds drooling yet ?
