First time having serious acne?

so lately i have been worried about my face. everytime im about to look at the mirror, i feel afraid because there will be new pimples popping out. i wonder why this happened so suddenly. i used to have pimples nearing my period. this time pimples start popping out few days before i had menses but it seems that it has still not gone away even after i have finished my period. it was never like this. i have been searching for good acne products to help clear my acne but i am still not sure. i have tried many things and looked at many videos on the internet. there are too many different advice.  i hope this acne will clear away soon. btw, tomorrow i will be going for a job interview!!!
