Constantly nauseous

Fanatic_Reflection
I have dibilitating anxiety and every day I'm nauseous. I can't take pills. What do I do? I tried medical weed but my asthma acts up and makes me even more nauseous.. I try tums but that only makes stomach acid go away. Sometimes it keeps me awake at night. What should I do? I've talked to doctors for 2 years and nothing has helped. I am underweight do have been for about a year and it's very difficult to eat. I drink a lot of water though.
