Terrible nausea, HEEEELP!!!!

I’ve had the worst nausea ever the past few weeks. Mostly in the morning or very late at night and little to no appetite. For anything, at all and everything i eat taste weird/different. I’ve noticed the nausea is worse on an empty stomach but everything that i do force myself to eat comes right back up... does anyone have any ideas on what can help 😣 I’m desperate.. I’ve lost 14 pounds and haven’t felt like myself.
