I’m miserable

Y’all I don’t know how to even do anything anymore. I’m 9 weeks today and for the past 4 weeks I’ve just wanted to sleep ALL DAY LONG. I’ve been nauseous and the only thing the relieve me of my nausea is eating. I’m sooo tired of eating all day long! I have 3 kids (ages 3 and twins 2 year olds) so I have to take care of them but dang is it hard to even get out of bed most days. When they go down for naps, I either take a long shower or I take a nap or even both sometimes 🤣🤣. Any ideas on how to get my energy up?
