Feeling so unprepared 😢

I’m 30 weeks and each day getting more and more stressed. I am having a family baby shower and friend baby shower which I’m very grateful for, but not until 4 weeks before my due date and then whatever I still need I’ll be shopping in holiday craziness, while hugely pregnant... does NOT sound appealing or fun at all :( I want to be patient but I’m hardcore nesting right now and I NEED to feel prepared. Which I don’t. I know I’ll order anything I don’t get from amazon but this is still driving me crazy. Any help, advice or comisery...
