What's wrong with me 😭😭

I feel VERY dizzy after I eat. I genuinely feel lethargic, drowsy, tired and weird most of the time!! I've had blood tests that came back ok.. just markers for an infection.

I have a appointment in the morning so hopefully they have more answers. I'm a mum of 3 I can't cope like this I have no energy I can't handle these dizzy spells most of the day etc it's weird!! Plus belly pain ahhh anyone have a idea what this could be?
