If I eat I feel like absolute crap. I puke up everything even if it something small, and if I don't eat I feel like crap. It's a lose lose situation. I also have a head cold. And on top of all that I can't sleep at all because my stomach hurts so bad and it's so uncomfortable major heart burn and acid reflux . Idk what to do I think I have the flu or something. All I know is I can't do anything. I'm just so ready for this to be over with.
