Nothing seems to work for me...

...and it's making me depressed. I've had minor acne since I was about 13 years old and I've tried most products available in my country yet I still have them. On very rare occassions, I can have one or two days when my face has almost covered, but it'll be ruined the next day. I am almost 19 years old right now and I am not confident because of acne. I avoid going outside unless I have to, because of my acne. It is affecting my life majorly.

The things I have done to remove/decrease my acne:

• Use various products (right now: Bioderma scrub, Bioderma Sebium H20, Bioderma Nourishing cream, Skinorent, Treclinac)
• Drink more than 3 litres of water everyday
• Scrub my face with water 3 or more times a day
• Change bedsheets every 3 days
• Stopped eating dairy, sugar and greasy products
• Eating a lot of vegetables and fruits. Eat at least 2 of each per day or more.
• Take showers every morning (hot showers for opening pores and a cold one in the end to close them up)
• Working out in the gym 3 days a week, if that helps in any way
• Not touching my face at all

I feel helpless. I want to go out and experience life and be happy the way I look. Is there anything else I can do to get rid of or decrease my acne?
