Cried in front of a stranger today

So I am 38.5 weeks pregnant holding my 22 month old (who by the way is 100th percentile so basically as big as a 4 year old.) While shopping at a breast pump store. The sales lady was trying to be kind and asked if my parents lived close by and will they be helping when baby comes. Yeap I cried. There is no way it is fair to tell a stranger, nope dad's passed on and my mom is newly paralyzed and is ill.

I was so overwhelmed already and then it hit me so hard that I am about to give birth in 3 days and nope my kid's are not going to be around their grandparents. Baby is being named after my dad. I am just hormonal and overwhelmed with everything right now and it made me feel so alone.
