Acne solutions for sensitive skin?

I am an 18 year old almost 19 year old male. I have had acne for as long as I can remember. Since freshman year of high school at least, and I graduated in 2012. I've tried different acne step processes, and most of them just seem to dry up my skin or don't really work. I'm pretty sure I have sensitive skin, I've never really been to a dermatologist, but I really just don't want to have to worry about acne anymore. I've gotten tired of it and have started using light foundations and makeups to cover my bad areas. I get big and small pimples still, daily, it's basically become a part of me. I want to start feeling confident and not have to worry about them. I've tried using Hydrogen Peroxide and for awhile it worked REALLY well, but now whenever I use it I think it makes it worse. I also have been working out everyday and have entirely changed my diet to healthy foods and lots of protein. Could this have something to do with it? I thought it would help. So far the best solution for me has been to just use water everyday to rinse it off, and then put on a simple moisturizer. Should I stop using moisturizers and just stop everything all together? I'm not sure what to do. Any home remedies or things that I can buy in a grocery store to create something would help. I just wish it would go away!
