Kinda worried about my health

I feel like I'm super super sleepy. This has been going on for a few days. I wake up sick to my stomach, and achey . Today I noticed I'm running short on my breath . I feel like I'm struggling to breathe a little. Then I've been getting little cramps here and there now it's kinda bad cramps. Along with some dizzy spells. I almost couldn't stay awake or relax at work... Any idea what this is?
