Every day recently has felt like a constant crash??

I got diagnosed with hypoglycemia like 6 or 7 years ago but as long as I’ve eaten 3 meals a day at relatively the same time and maintained a relatively healthy diet, it hasn’t taken over my life. But in the past few months, every morning I get really really shaky after eating breakfast (it literally doesn’t matter what I eat, complex carbs or protein or sugar or high fat) and start having heart palpitations, I get really tired and anxious and it basically keeps me from being productive for at least 4 hours. And in the past few days it’s basically lasted all day. I’m desperate for a solution at this point. Someone please tell me what to do.

Please don’t say that I’m not eating the right things for breakfast, I’ve tried such a variety of different types of nutritious foods. I’m worried that this isn’t even hypoglycemia related and that it’s something else entirely.
