So.. you've chosen to eat in a way that makes you miserable and now you're complaining it makes you miserable.
Diabetic friendly food (which.. you don't need tbh, because a basic healthy diet will do you and if you're genetically predisposed to develop T2 i hate to tell you this, but it will happen anyway if it's going to!)...does not have to be plain or bland or boring.
Scrambled eggs - pop in a finely chopped slice of smoked bacon in the pan first, get dry cure free range artisan whatever bacon, freeze it in slices so you don't have to eat a whole packet.
Or sling in some spring onions, or mushrooms, and some pepper or paprika or chilli powder.
Any of those options will add flavour and even the bacon option won't add much bad stuff, certainly non from a diabetic POV.
Serve it on a slice of brown, wholemeal seeded bread - you'll be much fuller for longer and feel happier!
It's sensible to be aware of salt but if you're NOT adding any salt at all to food you're making from scratch, you've quite probably not got anywhere near enough salt in your diet. We do NEED salt, the reason its such a risk is that it is in processed foods in large amounts, but those of us not living on processed foods do NOT need to cut it out of our cooking!
Salt is also a flavour enhancer, food will taste very boring and very bland without any!
Go stock a herbs and spices cupboard and try out flavours! You should also eat some fat, fat is not the enemy and if you're cutting out carbs and sugar, you really need to - fat and salt in moderation will make food taste SO much nicer and your brain will be so much more satisfied.
