I feel taken advantage of lately. No one really calls to ask to hang out or ask about my son. It's just been texts, phone calls and Facebook messages for a ride, watching kids, yelling at me for forgetting something they wanted. No one has taken one second to ask how I'm doing as a mom. Do I need a break? Would you like us to watch the baby so you can have time with your husband? Somewhere down the line the favor isn't returned. And the appreciation isn't even existent. Maybe I'm over reacting. Maybe it's postpartum depression? I'm so hurt I just want to cry and scream! What do I do? How do I go about raising my child without acting like one when it comes to other people's selfishness?
