SOS- Sick 12 weeks pregnant

I’m sitting in the bathroom at work crying/throwing up because I’m so mentally exhausted. I swear I’ve been sick since I conceived and throw up everytime I eat!!!!! Or don’t eat. Wake up- puke. No matter what I eat- I throw up. I’m so miserable and frustrated this is so hard. I’m so grateful please don’t get me wrong but I’m so sick and exhausted all the time and I’m just frustrated. I’ve tried every diet, tried Vitamin B and Unisom nothing is helping 😭😭😭😭😭 any advice I’m desperate
