frustrated over acne

The purging from tretinoin hasn't finish. Now both of my cheek are full with red dots. Red, inflamed papules staring back at me everytime I look into the mirror. And to make things worse, I have 2 nodules on my chin, also inflamed. Tried masking it but comes to a fail. Hope I could conceal my pimples, tonight is my cousin's wedding and tomorrow is my bf's birthday
