Morning Sickness

This is my 2nd pregnancy and currently week 7 and having morning sickness. I keep throwing out whatever i eat or drink. Feeling giddy and tired everyday.. i cant rest well too. I knew this is common, but it is destructing my daily life. I cant go out, whenever i sit inside the car, i feel like vomiting. I cant focus, once i focus i feel like throwing out again 😔 what should i do now?
