No one to talk to

Hey mamas, I'm really struggling with feeling like I have no one to talk to. My partner and I have been really rocky since our daughter was born (we are working on things) and I just feel like I have no one to talk to. I think the main issue for me is I don't want to "bad mouth" my partner to my friends or family, or even mum's group, as they all know him. It's not even necessarily that I have bad stuff to say about him, it's just hard to admit that we're struggling. I'm in therapy but I struggle to get too deep with my psychologist and have been focusing on working on myself so I can be a better partner and cope better with my anxiety. I'm just feeling really lonely right now.
