I'm at a loss please help

t123
Almost 15 weeks pregnant. 
Gets worse by day, been prescribed every medication possible nothing works anymore or ever has. 
Been in and out of hospital - go to the hospital for IV, feel better for about half a day and back to feeling the same and I just don't wanna keep going back but that's the only thing that helps.
I've done everything in the books for helping this, I am just so tired of just being sent back and forth for IV and home. I don't know what to feel think or do.. I cry so much and I'm just miserable and tired. 
I know I have a long way, idk how to deal. Please help me....
