I fed her from both breasts...dry diaper...no colic like there is none…

I fed her from both breasts...dry diaper...no colic like there is none...but she can't fall asleep...she seems to be waking up again and again...like something is not letting her sleep. I tried to feed her again but it was already dripping from the breast...and then she vomits, but sucks on the pacifier so actively as if I didn't feed her at all ? what is this ?
