Any mummies has this postpartum depression symptom?

Whenever my in law family wanted to close to my baby, i will be very pissed off. I dont like my mil close to her or whenever she come to our place. the kids in the family love my baby so much and always surrounded us as i am carrying my baby, i feel so suffocated. my Mil has the access to our house and she will just come over quietly without inform or even knock and she will just open door herself like that. I know i shouldnt feel so whenever ppl trying to occupied my baby, but i just dont like it. Not sure if this is consider one of the depression symptom.. and i am trying to overcome it and be open minded abit but 8months already i still feels the same. #pleasehelp sigh…
