i feel like I'm on the verge of a mental breakdown.

I'm just so stressed out with the baby coming soon in April and money... I feel like my hormones are getting the best of me again. SO is picking fights with me. I'm just so irritated I want to just sit in a dark room by myself all fucking day. Why am I so sad right now???? I feel sooooo emotionally overwhelmed right now I can't even explain it. I literally feel like My chest is about to explode.
