Third trimester pits

This pregnancy was going fine until recently. I don’t know what is the world is happening. I am sooo emotional, depressed, overwhelmed, not the nicest wife I could be, my almost 2 year old who is a great sleeper/napper now wakes up for hours in the middle of the night, screams at bed and nap time, I am so tired all the time but can’t sleep. I’m so excited to meet my baby girl but terrified of PPD again. Not sleeping. Not having energy for my son. Tell me I’m not alone here ladies 😰
