Overwhelmed with baby

Just so every mom knows . We are all overwhelmed. I’m so sorry because I know it sucks. Feel free to vent . No one’s alone I know I post anonymously but if anyone needs anything I’m here !!!

My vent: my baby just screamed bloody murder for an hour and nothing I did was helping until she had cried enough to take sharp breaths every couple breathes and fall asleep . Then I cried for just about her whole 30min nap because I felt defeated and overwhelmed and felt like I did nothing right . Now she is giggling at every little thing that she sees . (Ps she is almost four months and no it wasn’t teething a tummy ache gas her clothes no fever wasn’t hungry didn’t wanna be put down didn’t wanna be held checked her head to toe nothing showed to be wrong but she screamed like when the nurse literally JABBED Her full force for her 2m shots and she had bruises for two weeks from it )
