I feel terrible

The other day i snapped, i was so tired and i couldn't take it anymore, my 2½months old baby was crying and i wasn't able to calm him down so i started to cry a lot, i put baby down and cry while staring at him stressed cause i couldn't understand what he needed, and telling him i couldn't understand him and repeating at myself that i'm not able to do this (being a parent).

Baby stoped crying and just stared at me while i was crying.

I feel so bad about it, i don't know if that made him feel bad or sad or confused. Ever since that day he is being acting more serious, he does not smile at me as much as he used to. He just stares at me.

I'm worried i might have broken a little the bond between us o that he does not feel as safe with me as he used to. I'm so worried that i might have made him feel unwanted or something.

Being a mom nd all the changes has been really hard and i've feel bad a lot but i think this time it might have affected my little boy.
