Constant sickness

I'm 22 weeks and 2 days pregnant and I am still being sick every. Single. Day. I found out at 6 weeks and have had sickness every day since then, some days it's just constant nausea and other days I'm being sick at least once or twice a day. I feel like this is never going to end, I sound like a terrible person but I'm dreading her being born because I'll feel awful through lack of sleep & now I feel awful because of the sickness, I'll never get to feel normal. Absolutely nothing helps, tablets haven't helped (they occasionally take the feel of nausea away but don't stop sickness), no food or drink, nothing with ginger etc, I dunno what else to do. I have a 3 year old so I really don't have the time to lie in bed feeling sorry for myself. It's making me so depressed all the time 😓😓
