Harder than I thought

I am in week 7 of my first pregnancy and I feel like it is way harder than I thought it was going to be. I’m exhausted and can barely make it through a day without napping. I’m hungry but also get super nauseous in the evenings when I’m trying to go to sleep and the mood swings are unreal. I feel like I’m permanently on the verge of tears. I’ve heard the first trimester is the hardest but is anyone else in the same boat and feeling like this! It also doesn’t help that we haven’t told anyone yet so even though my husband is amazing not being able to complain or get help from my best friend, teaching partner, etc. makes it even harder.

Anyone else feeling this way too? Or any advice or encouragement from those who have made it through?
