Scarring and acne. Feeling of ugliness.

First thing sorry for my English Now here's a description of my problem I am suffering from acne from last 3 to 4 years. After trying homeopathic treatment for almost 11 months I cleared up so much but as I am having a bad habit to pick up the acne caused scarring in my face specially on my T zone . I still get acne of large sizes but when I am on proper diet and sleep they occur in very small amount . I don't want to take any pills (accurate or antibiotics) and want a solution for scarring. Can microdermabrasion,laser and microneedling helps to clear my scars and what are the sideffects and cost and where to find a good doctor for all the procedure. PS:- acne and scarring changed my whole life from performance to my grades in college. The psychological effects of having acne are very devastating as it change the entire thinking of a person. From depression,anxiety, self hate and loosing all the interest in any activity,isolation end a feeling of ugliness.
