Getting aggravated

Please no negative comments!! Please tell me I'm not the only one that gets agitated every now and then. Last night I was getting aggravated at 4 this morning when he woke up for a feeding cause he wouldn't go back to sleep after and I'm so sleep deprived. I had to walk away from him while he screamed, I would never hurt my baby in a million years. I do everything for him, my fiancé works 10 hours a day 6 days a week so I don't expect him to get up with him in the night so I do and i literally get 3 hours of sleep a night. Please tell me I'm not the only one that gets aggravated like this? I'm a ftm and I don't wanna be like this. Please give any advice you have but no negative comments
