The best thing if it is possible is for you to see a dermatologist or skincare clinic (even a lot of beauty salons these days are educated in skincare or have a specialist section). This is because you need a little guidance with your skin so that you don't damage it too early on as this could worsen it. I have had acne from a young age and found the best results from a dermatologist. A lot of them also offer discounts for students as well.
You could also try a few things yourself, like eliminating acne causing foods from your diet, introducing foods/vitamins that are good for skin, drinking plenty of water to make sure your skin is hydrated, try not to stress out too much as this has a big effect on skin.
If you are using products, do try to use good, recommendable products as some of the cheap ones do more harm than good to some people. Cleanse twice a day. Try to stop using different products all the time or too many at once as ofttimes a routine occurs where we do not allow our skin to get used to one product, decide it doesn't work and move on to the next.

You are young dear. Don't let acne get in your way. Try natural products first before you use those with chemicals. One which I would recommend is Banish ( https://www.banishacnescars.com/collections/all ). They use natural ingredients and if they don't work well with your skin, simply return it to them.

Go out with friends. Enjoy your youth. Best of luck and I wish you'll find that one product which suits you.

Oh, darling! I understand. Perhaps go to the derm and see if it hormonal in nature. If so, perhaps going on birth control or Spiro may help you. In the meantime, you could try getting a facial.
