I feel like the worst mother in this planet 😭

As

My daughter is 15 months old. I was having a rough night. I am naturally a very patient and loving person. I’ve never really raised my voice at my daughter besides to tell her no. Or Harlow no! Really stern. I was going to put her to bed, I rock her and then lay her down. I felt her diaper was wet even though she just bathed and I put a fresh one on. Well it was barely wet but I have this thing where I just cannot put her to bed with any kind of wet diaper. She must have a fresh diaper for bed. I laid her in her crib for ONE second while I ran into the living room to grab butt paste. She has severe separation anxiety. She erupted in a scream so loud and hard it pretty much made her hyperventilate. I picked her up laid her on her diaper pad, she is still screaming bloody murder cause I left her. She’s crying so hard she just Vomits EVERYWHERE. After her bath, after the only clean pajamas she had on.And I lose it. I picked her up I sat her on the ground and walked out of her room and just screamed. I have NEVER done that before I don’t even know what happened. I feel like the worst mother in this world, while my baby sit on her floor covered in puke and I’m having a mental breakdown in hallway. She was trying to crawl to me😭😭 she needed me. I’m the worst ever. I gave her another bath and now I’m putting her to bed. I’m just so upset
