Am just a hormonal batch?

Am just a hormonal batch?

So I was talking to my mom. She told me that my grandparents are having a triple birthday party for my brother, grandpa, and uncle on feb 12th. I told her ok I will do my best to make it. She got mad and was like I don't understand why you just can't commit to it right now. I told her I really want to make it. It's just that's like a month from my due date. I'm so exhausted already. I don't sleep well at all. Dh just got a job so I am chasing my 17 month old around all day. (I know many women do this and are fine and I praise them I'm just getting used to it.) also it's an hour and a half away. We're on a very tight budget and that's a ton of gas and dd HATES the car. And I can only drive because dh doesn't have a license right now, the car really f**ks my back up too. She told me well fine if people ask me I'll tell them you're probably not coming then. I said no just say that I will try to make it. I don't know how it'll be in a month that's why I don't want to say yes and then back out. She said fine and then hung up. I started balling my eyes out. I felt like she was being so mean. I know they want to see dd but I'm just so exhausted all the time.
