i just want it to stop. 😭

I'm 7 weeks pregnant and i have been throwing up daily since Saturday. I will eat but in a couple hours it comes right back up. Water makes me gag as soon as it touches my throat, i know im dehydrated because my head has been killing me for 4 days straight. i cant keep my eyes open cuz it hurts more to have them open. Walking around is unbearable, instant nausea as soon as i straighten my torso and extreme dizziness from the headache. I don't renember ever feeling like this with my other 2. I'm just so miserable from feeling sick all the time. 😭😭
