Severe all day nausea and sickness at 7 weeks

I’m really struggling with morning sickness all day and night now - for a bout a week. I’ve tried everything I can think of (ginger, crackers, sea bands and even medication the DR gave me cyclizine) - but I’m still really struggling a vomiting multiple times a day. I’m keeping fluids down which is good but I’m so paranoid I’m neglecting the baby because I can’t hardly eat ☹️ I’ve lost a fair bit of weight and I’m already quite slim so I’m just miserable and struggling 😭

Any other medication I can try?

I feel so guilty for feeling so negative because I’ve wanted to be pregnant for so long but it’s just really difficult ☹️ x
