Am I selfish?

My daughter is 3 months old. I am a mother of 3 and my 3 month old is so attatched to me. I feel overwhelmed or something. I just want some alone time. I can’t sit her down without her freakin out and bawling. Her dad doesn’t help much. Well not as much as I think he should. I constantly have her and can never get ready without having to hold her because she won’t let me set her down. If I give her to her dad he just sits on his damn phone and lets her cry. Am I selfish for just wanting some time to myself. 😭 I am so frustrated and feel like I’m taking it out on my other 2 kids. I honestly don’t mean to. I love them all but I am only one person.
