Acne cure theories

I feel like I am going crazy because of my acne, well not because of acne but mostly because the majority of the population dont or just rarely have it; so its a Huge disadvantege for me and I belive for every sufferers.

So the thing is I'd like to list the theories to cure acne but on the web I cant really find theories but mostly general (batshit and bullshit) information.

I'd greatly appreaciate if you could post your theories/cures or the ones you have found so anyone who enters this topic will see them all at one place (a word, sentence or even pages long I dont care but make it comprehensible , but it can be detailed too).

Heres the list:

B5 deficiency theory

Theories about Diet

Caused by toxins

Liver problems

Hormone imbalance, especially for women, including estrogen dominance and PCOS

Zinc Deficiency

Widespread Inflammation

Thyroid problem

Insulin intolerace

Ehh... What now?

Okay now I am desperate... I am just sick of all the lies and scams on the internet about acne. I either find some bullshit general informaton for people who never actually had or just rarely have any pimples. So all that "healthy diet, exercises" and other stuff is nice but I rarely eat junk food and I go to the gym 4 times a week but I still have this stubborn acne and no matter what product I try it just doesnt work in the long term.

I always think of my friend who has 99% clear skin (always had) but his diet is way worse than mine. Meaning that he usually eats junk food on every second day or so and never misses a day without chocolate. He is kinda muscular (so am I) but anyhow his diet does NOT effect his skin.

And I've seen many obese people around and not everyone of them has acne. Also if diet could cure acne, someone would have found a suppliment which works...

My point is I have no idea where to turn to...
Changing diet doesnt seem to work, dermatologists cant offer a real help, over the counter products are not working at all or just to a point so I cant trust companies either, I already tried some household products without any success.

So what now? Maybe I should go try some Eastern ways to cure acne or what?

Crush

I am 19 years old, still at school and like many other people I have a crush on one of my girl (just to be clear lol) classmates.

The actual problem is that like most of you I also suffer from this "extraordinary" condition called acne (5 years...) and even if its not that bad it can and it still destroys my self confidence everytime I get a new spot or just look into the mirror and realise that my skin still looks much worse then the 95% of my classmates. Well maybe I shouldnt compare my skin to others who have perfect or just close to perfect skin but still I just feel terrible and different... Lately I get depressed a lot because of my face and everytime I look at or think about my crush, first I feel nervous then I feel a great anger because I know I shouldnt even try to get her because of my face so then I get depressed and I either smoke (if its during school) or I go to the gym and try to release pressure there.

Anyway I'd just like to know what do you do when you have a crush on someone who looks much better then you and seems unreachable...
