Severe morning sickness

I have pretty severe morning sickness and have for just over a week now. I'm 8 weeks pregnant and can barely keep anything down. I tried ginger biscuits, dry toast, dry crackers.. None of it seems to work for me! Dry crackers was working but this morning I was actually forced to get off of the bus and was sick on someone's flowers outside their home :( I was stranded in a different town for ages and had to call my partner who then left work to come and fetch me. How can I handle this sickness? I get it all day, everyday
