Morning sickness is so bad, 7w 6d

It is the worst feeling I have ever experienced. It started at just FOUR weeks, wasn't horrible, then once I hit 7w 4d, it is just getting worse and worse. I had to quit my job because of how sick I am constantly. I was prescribed Diclegis for nausea which would have been $158 if my insurance didn't cover it, even has a cute little smiling pregnant lady on the pill... didn't work. I can't kiss my SO or have sex, even him hugging me makes me feel sick, the warmth that comes off him... even getting up to get myself a drink is just a bad time. I puke once every morning, after my diarrhea attack, after that I'm constantly nauseous and feel hungover. I am getting so depressed and my anxiety is coming full force. I'm already on an anti-depressant but it seems to not be working anymore. I do manage to keep some food and water down, thankfully. When does this end? Who else has it this bad? pregnancy is not fun, I do not like it. I love my child in there though, and I hope to have a healthy baby. But baking him/her is just not fun. I'm already ready for this baby to be born.
