I feel terrible😰

I have literally been crying for an hour. I feel like the worst mom in the entire world. I was taking a nap and my daughter was on side of me, her daddy was supposed to be sitting up with her but had walked out the room to go get something. I wake up and she's screaming crying hysterically I start freaking out and find her in the crack of the bed. As soon as I picked her up she was completely fine but I can't help but to feel like the most terrible human being in the whole world. Anything could have happen. I can't stop crying. I need tips on how to get your baby to stay asleep in the crib.. she won't stay asleep in there for any more than 45 min but I am not sleeping in the bed with her anymore a day in my life. I would rather stay up every single day and night with her.
