Can’t stop crying

I gave birth to my boy on Saturday 16/3/19 I’m just so emotional. I can’t stop crying. I think I’m doing everything wrong, I constantly think something is going to happen to him. I’m scared that he doesn’t like me. My boyfriend kissed me properly for the first time in months and I burst out into tears.

The first song I heard after giving birth I listen to cry by myself when I’m gone alone. Is it normal to be this emotional?!
