Whats face food?? Food that helps spots and congested skin? Basically food that will improve my skin?

Out of nowhere the past several months I've been suffering a little bit of acne! It was worse last month but I've been to the doctors 3 times and he gave me 2 different pills, creams and a tablet to help. I still have a few spots and my face has the red dots from where my spots were when they were bad a moth or two ago. I really don't wanna wear make up to cover it and i'm so self conscious about spots. The next step is to go to the dermatologist but I've never suffered spots like this in my life and although I was going through a move over seas in May I suffered stress and was home sick I've calmed down the past 2 months and I'm happy so I'm hoping it's just a phase instead of paying for a dermo! But spots are still occurring!! I hate it :( I want fresh looking skin now that it's early summer I don't wanna spent it covering up my skin.. or worrying about it.. I'm drinking loads of water as normal, and I eat loads of fruit and veg, I'm taking vitamins for skin and fish oil.. and I'm excersising every day what else can I do? I use cleanser morning and night, I use moisturizer, I ex foliate every so often and all my products are oil free.... ahhhhh help?
