Is it ok to be absolutely useless?

I've hit little over 6 weeks now and nausea hit me like I didn't expect. I've always been really bad with nausea, though I don't want to just accept that as a fact. I'll wonder if maybe it's me who's making it worse by focussing on the fact of my being nauseous. I have periodic moments of relief and I'll be productive. I'm not an ambitious person but I'm neither am I lazy by any means. With this ongoing nauseousness, I can't seem to do 𝘢𝘯𝘺𝘵𝘩𝘪𝘯𝘨. I feel so pathetic and I can't imagine this going on for 6 more weeks. Will this alleviate as each week passes? Practically all I've done other than some dishes and laundry is lay on the floor and pet the dog, sit outside for like 5 mins at a time and come back in and sip tea and just stare out the window. Reading, doing art, cleaning, calling family, going on nature trails, cooking and enjoying my food has been pretty much cut out the past few days and I feel like I might be going crazy. Even typing this makes me somewhat queasy. Mind you I am careful about the foods I'm eating but I'm eating a lot less than I usually do and unfortunately I throw up probably half of it each day.

Edit: Thank you everyone! I really do appreciate all your support. Made me realize I'm not alone 😁. I wish you all the best in your journeys! 🥰
