Can the doctor prescribe me nausea medication ?

So im 8 weeks pregnant and i cant eat at all nothing im losing sooo much weight getting so skinny im so terrified and upset that i am. Always been thick alittle bit... i cant eat for my life this week ... i was okay for about 2 weeks ago but it came back again and even stronger. I guess my baby doesnt want anything that i eat .. or not hungry 🙄😭😭😭😩 idk what to do.. i tried everything.. the seabands dont work on me i need medication
