37w2d and feeling lonely

I know I’m not completely alone as I have my partner and family and my little one moving about in me but I feel lonely in the sense that I don’t have anyone to talk to, my bestfriends have stopped speaking to me for over 3 weeks now and I do not have a clue as to why and all my other mates have their own close friends so I barely see them. I’ve just moved into a new place and it feels so empty that I’m just stuck with my own thoughts until my partner comes home and even then he barely speaks to me. Am I falling into depression ? Has anyone had this happen ?
