8 months PP, can I get PPD?

🌞♌️ 🌑♎️ ⬆️♏️
What are signs or symptoms other than feeling sad? Here recently I get bouts of anger and just go off on every one and I just feel like I want to run away and not take care of my son. I feel like my husband barely wants to help. I feel like he's away all day at work and gets a break. Never had to wake up with him. Even when I work I still make hisbittles at night and get up with him. And it makes me want to just run off. I don't feel sad all the time it just comes and goes.
