Pregnancy is weird..

I woke up this morning and for no reason at all I just feel so emotional and sad about everything. I just want to cry. I'm 37 weeks and I guess I'm just realizing how close I am to meeting my baby and it's freaking me out idk. I have no reason to be sad or emotional, it's a good morning but I just wanna curl up in a blanket and cry. :( Wtf
