Grief and new baby

Hi all. Would love to hear if anyone else has experienced anything similar to me since i am feeling quite depressed and alone lately. I lost my mother two months before having my second baby ( a little girl who is really a great baby ) she is almost four months old and i feel my grief has become worse and worse possibly even depression and it’s affecting my bonding with the baby. I tried to keep mysled together while pregnant to protect my baby and now that she is here the loss of my mother has become unbearable. I don’t enjoy my baby the way i should be or how i did with my first born atleast bc i am mourning ... finding it very hard to be a mom without any help or mother ( i also don’t have father or mother in law so we don’t have much help at all ) anyway would just like to hear other people’s stories and how you dealt with I️t and a newborn .. especially how you bonded with the baby while going through this.
