Some days I feel like I'm drowning and nobody sees it

Everyone thinks I've got it together. Good job, nice house, healthy kids. But most mornings I wake up with this weight on my chest that doesn't go away til like noon. My wife is great but I don't want to dump my stuff on her all the time. I'm trying to just push through but some days are harder than others. Started talking to a therapist last month which helps a little. Just needed to write this out somewhere I guess.
