I’m struggling

One day I feel okay and my nausea and vomiting isn’t so bad and one day I’m waking up out of my sleep to run to the bathroom and throw up and then it just continues for the rest of the day. I am 10 weeks and have been dealing with this since 5 weeks it’s like if I have one good day I know the next day I’m going to be sick. I am so weak and tired. I am on prescription medicine but it’s not working as well as before. I’m struggling to just get through the day some days.
