Feeling alone

Hi…my baby is almost one month and so far my mum was here from Italy to help me. She’s gone back from one week and since she left I feel alone,all my family is back home so I only have my boyfriend here(he’s really supportive and helpful in everything). I cry everyday because I don’t have no one else to help us,my boyfriend goes to work at 5pm until 11pm and in that moment I’m alone with the baby and I feel more lonely,my family call me but it’s not the same,I’m not able to do anything in the afternoon because I’m scared to leave the baby not near me(even if I have a monitor). Everything I was enjoying before pregnancy now I don’t anymore, all ‘friends’ now they are not contacting me anymore(just called at the beginning when the baby was born),I know there are also children centre to meet other parents but I don’t even want to go out to meet new people. I’m really struggling because I keep crying for loneliness and feel like I can’t do it and there’s never an end to this,in the night I keep waking up to check on the baby as I’m scared of something happening to him while he’s sleeping so I’m not even sleeping properly. I don’t even feel like going out for a walk,my boyfriend push me to go with him for a walk and the baby but I don’t feel like going out of the house. I don’t know if it’s depression post partum but anyone in the same situation?
