morning sickness at 26 weeks

I've had morning sickness since I was 6 weeks so we're going on 20 weeks of morning sickness 😭🙄 I was on zofran but for the past week it just seems to have stopped working. Are there any tips/tricks that help you guys with ms? I just want to curl in a ball and cry because I feel like I can't work, can't get off the couch and I feel so worthless with my husband doing everything ☹️
