EXTREMELY EMOTIONAL!?????

I'm currently 38+2 and the last 24 hours I have been so so emotional.

I can not stop crying at certain things.

My 3yr old is currently going through a stage where she's just loving dad and I feel so rejected but the last 24hrs have been so bad I have just felt so forgotten about and I can't stop crying about it, I woke up in the middle of the night just to instantly start crying.

Usually I'm not THIS emotional....

Iv been reading you can get emotional before labour but wondering if it's true and if anyone else got extremely sad/emotional/moody before labour and if so how long did u notice it before your labour started ?
