Acne Treatment Solution and Prevention

I did a search and I know of people have asked similar questions before, but still, I would like to get direct opinions.

I have been suffering from acne since I was 12, and until I was 16 the situation was not so unbearable, the pimples focus mainly on my forehead and chin before my monthly period, and they usually heal after my period.

However since I started working part time when I was 16, due to stress, and I started to get serious break outs on the other area of my face, and some of them are hard pimples that seems impossible to get away. Every spots that I get leaves deep red colour scaring and now no where in my skins is clear except my eye area.

Now I am 20, and the situation still continues, I believe my puberty has far gone and ruled out the cause of imbalance in hormones. During this time I have tried almost every product that I could get from the market, from creme de la mer, SK2..etc, nothing really works.

So I am considering laser treatment. Worth it? and How much?
btw, I am worry that I would be ashamed by my vanity when if I really go into a hospital and do my treatment.. people are going there to treat their skin cancer or something but I am here to cure my acne?…. this might sounds really stupid but my skin is giving me emotional distress and really lowered my confidence…
This is so contradiction anyway I am just moaning..
