Anyone else feel lonely even when surrounded by family?

I love my wife and kids more than anything but man, some nights I just feel isolated. Like nobody really gets what's going on in my head. My buddies mostly just talk about football and work. I can't seem to have real conversations with anyone. Started going to therapy last month because I realized I had no one to talk to about the actual hard stuff. It's helping but it's slow. Just wondering if this is normal or if I'm the only one feeling this way.
