Just need someone 2 talk to😞

I have major depression had it since 9th grade .

I just recently had my second baby 5 days ago. The postpartum depression always hits much worse since I had depression already. I have a 19 month old little girl and now a newborn son... we been home for 2 days and I already feel like giving up 😞 it’s so hard. I’m low on sleep and I’m trying my best not to get frustrated or mad or cry. He wakes up every 2 hours to eat I’m so tired and sleepy. 😞 my 19 month old has been acting out since we brought him home because she’s jealous she’s a baby herself so she doesn’t understand what’s going on. I feel like a horrible mother cause I don’t want her to think we forgot about her. 😞 I just want to give up already I’m started to think maybe we should’ve waited to have another baby & I hate thinking that but I’m just tired rn 😞
