depression or just tired ?

Kiara
I'll officially be 9 months pregnant next Thursday but I have just been so unhappy I mean don't get me wrong I'm obsessed with my daughter and I can't wait for her arrival but being pregnant is overwhelming me now like all I can fit in is leggings and tee shirts my shoes don't fit and I'm eating all the time I just feel so unhappy and idk if that's a sign of depression or I'm just very overwhelmed
