I don't enjoy it 70% of the time

I work two jobs to support my wife and 4 month old son. The only time I see him is a few times a week to put him to bed once he's hit his wall. He cries and screams and doesn't calm down. If he does, he picks right back up after a few minutes. I don't enjoy it, I feel fucking worthless and frankly, it makes me want to have my wife do everything. It's been the last month of this and it's been fucking terrible. I had to rant, this fucking blows, hard.
