13 weeks and MISERABLE!!

Lucy • Married for almost 6 years. First time mommy.
I tried to hold off and not complain too much but I'm freaking miserable!! If I'm not vomiting, I feel like I'm about it. If I'm not having diarrhea, I feel like I'm about to. If I don't have horrible stomach pains from the INSANE amount of gas I have, then it feels like im about it. Also, forgot to mention there is CONSTANTLY a huge lump in my throat that feels like vomit. Like food is stuck there right there in my throat alllll the mother effing time. And no matter if I try to throw up or if o haven't eaten it's always there. I feel so tired all the time and dizzy to top it off. My doctor says "it means the baby is very healthy. You might just have to come in for fluids once a week" UGHHHHH!!!!! And all I keep hearing is "oh it's such a blessing" or "oh you'll forget all about that when you're holding your baby" I seriously doubt I'll forget how HORRENDOUS the last 13 weeks have been. Please someone help! Advice, remedies, anything.
