Depressed on maternity leave

It’s driving me crazy because I should be sooo happy waiting for my baby girl any day! I’m 37 weeks and started my leave this week. I normally LOVE being home and home making and cooking etc I love to read and decorate and garden but I don’t feel like doing ANY of that! What’s wrong with me?! I just wanna go to bed and do nothing (on top of that hormones making me super horny is annoying). Why am I not excited and nesting?? Her room is done clothes are washed so I’m just so depressed and lonely 😞 idk what to do
