When does it stop being “baby blues” I just feel so empty inside.. the father of my children keeps trying to play mind games leaving weeks at a time after making me deal with this pregnancy myself.. all the excuses and I still try to keep the peace and leave the door open because (maybe he’s going through something)... but IM going through shit.. I feel empty like a pain is in the back of my chest and I’m trying to stay strong but it’s so hard
