Getting Depressed Due to Nausea

I will be 14 weeks on Monday and the nausea seems to be getting worse, rather than better. Being sick for 11 weeks straight has sucked every ounce of joy out of this very desired pregnancy. My first pregnancy was a breeze, and this time is just so different. The Zofran pills don’t seem to be helping my nausea, but I haven’t thrown up at least since starting them. It’s like waking up every day, just to wish to be back asleep (if I can even sleep). How do women NOT get severely depressed being so sick? This is ridiculous, there is no functioning😔. I feel guilty for feeling this way.
