acne attack! ? please help...

I have had skin problems for a long time now - about 6 years. I have normal/combination skin but I have had many problems with acne outbursts since age 12/13 (I am now 19). I have had all kinds of pimples - from the painful, hard ones (cystic acne) to small, puss-filled ones. My face is now covered with red marks and some depressed scars as a result.

I stopped consuming cow's milk products for several years as this seemed to make my situation better, but my skin still didn't stay completely clear. This summer (I lived in the south of France until 2 months ago, now I live in Holland where it is a lot colder...) my skin cleared up entirely for the first time, and I could even consume cow's milk products again without any side effects.

However, since I moved to Holland, my skin has slowly been getting worse again, but nothing I couldn't deal with, until now. About 2 days ago I got a sudden outburst of a huge amount of pimples all over my face (mostly the middle) - they're quite small, some are red and some are just filled with puss. It keeps getting worse and I have no idea what to do... It's making me extremely angry, frustrated, and restless. I feel like it might be because of my current emotional state (I recently broke up with my boyfriend of 2 and a half years, and I am back home in France now for a little while which is difficult because there are reminders of him and my old life everywhere around).

Can somebody help me? Does anybody know what I could take to help this problem most likely caused by my emotions? (both help for the current acne 'attack' or the long-term problem is welcome...)

Thank you! It's ridiculous how much this affects my already 'fjhdfhkl;fl/dafferwfjkwnlfmeke' (for lack of a better description) emotional state...
