Feeling depressed

I’m 37 weeks pregnant and I have a 2 year old. Dealing with my 2 year old makes me feel like I don’t want to “deal” with another baby on top of my 2 year old. My 2 year old drives me crazy some days & I’m pretty much a single mom. My son always gives his dad a hard time at bed time & nap times so I always have to take over. My son always prefers me to calm him down over his dad, if his dad tries to soothe him he’ll just cry harder for me asking for mommy. I’m always the one spending time with my 2 year old because my spouse works 2 on 2 out of town, he’s barely home. 😪

I wish I had a spouse who was always there & can actually help out… I feel like my 2 year old is starting to act out. He doesn’t listen, he’s bratty. Typical 2 year old probably but it makes me depressed that I’m having another baby. I wish I didn’t feel this way.
