You have severe acnes. From your email, you tried different methods but in vain. I can see that you are very stressful.
Your history looks pretty normal. I do not think that your acnes are due to specific triggers.
It is suggested that you take oral medicines for your acnes. Do see a family doctor or a dermatologist. Earlier treatment of acnes can reduce the complications eg acne scarring, and can reduce your emotional stress.
Some other friendly advice: sleep early, keep a healthy diet, and regular exercises are important for health. Wish you get well soon.
