Depressed 😔

Danielle
I'm in the thick of my first trimester with baby number two... Super nauseous and exhausted all day. I have a two and a half year old boy who has energy for days, and I work from home, so I can't exactly rest. I feel like I'm failing my son, and last night I just held him and cried because I feel like I've been yelling at him all day for the past few days. He has definitely been acting up (hitting me, saying no to everything, screaming at the top of his lungs when he doesn't get his way), and I know I need more patience, but last night I just lost it. What business do I have having ANOTHER child? I feel so overwhelmed as it is, I have no clue how we're going to make it through this whole pregnancy and beyond :(.
My son is the only grandchild on both sides of mine and my husbands family, and he has total only child syndrome. He's a sweet, smart kid, but he demands attentions from anyone and everyone. I know a sibling will keep him company and show him the reality that the world doesn't revolve around him, and eventually we'll figure it out. But right now this just sucks :(. He'll be almost 3 and a half by the time this baby is born... Praying he adjusts well, and praying I don't lose all my marbles along the way.
