Morning sickness remedies please

I am 12 weeks 2 days have been suffering from morning sickness since about week 5. I can't barely move without feeling absolutely awful. I've tried ginger, ginger candies, trunatal nausea pills, Gatorade, acupressure bracelets... Nothing's helping. My obgyn prescribed Diclegis but my insurance won't cover it.  I want to cry. Any other suggestions?  I'm also extremely fatigued. I feel like I haven't been able to live my life for the last seven weeks.  My apartment is an absolute mess and I can barely leave my couch to go to the bathroom let alone clean. I feel awful.
