Depression hit me harder after becoming a dad

Wasn't really struggling before but somewhere in the last few years after my first kid was born it just set in. Fatigue that sleep doesn't fix. Going through motions with my family but not really feeling present. I'll be playing with my kids and my brain is just elsewhere. I feel guilty about it which makes it worse. Haven't talked to anyone about this because I feel like I should just be grateful and happy but that's not how this works apparently. Anyone been through something similar and actually got better?
