Undecided Question

Ok well i am 12, im not even going to lie about how old i am cos i think its got to a point where i just cant take it any more.
When i was 11 i started wearing makeup, and a LOT of it. I know it was stupid so i dont need anyone to tell me that. Anyway so i just started getting blackheads, no biggie. Then i started getting whiteheads, so when i turned 12 i asked to get the clinique 3 step skin care kit since i heard so many good things about it. After about 2 days i started breaking out like CRAZZZY im not joking my whole face was so red and puffy, i stayed at home until it got better. It didnt get better so i stopped using it and used neautrogena and stuff like that, it has been about 6 months since that happened and i have the worst skin you could imagine. People ask me if i was my face (people i dont even know), they take pitty on me and i cant stand it. I have blackheads, whiteheads and pimples.
YES i have started my period about 2 months ago so maybe that could also be the cause but i really cannot stand my skin anymore. I have been eating really healthy, i am drinking lots of water, doing lots of exercise and taking my makeup off (since i cannot go out without it, stupid right since im so young, but if i dont i have no confidence) and i cleanse, tone, moisturize, exfoliate once a week, mask ETC but NOTHING is working.

Please can someone help me

I tried going to my GP but they are like booked for 3 months and i really cant stand it please can someone help me…
