Nauseous and crying

I can't stop crying. I am not good with nausea. The unisom and B6 trick is not working anymore and i'm going to have to drop classes and stop working which means the money I saved for not working after the baby is born is going to have to be used now. My boyfriend tries to be supportive but he doesn't know how to clean or cook and I am stuck in bed wishing I could just die. I had an abortion not too long ago because the nausea was too much to handle. I'm trying so hard to fight this but when you're stuck in bed 24/7, it starts to mess with you. 
How do I get through this? What if this lasts throughout the whole pregnancy? I can't do it. I can't.
