Seems like I've tried every method and I'm still an A cup after 4 years. Should I kill myself.

Absolutely not. What methods have you tried?. It's quite possible that your T isn't suppressed enough to change the T/E2 (testosterone/estradiol) ratio. There's a multitude of reasons for lack of growth. Generally, I find that insulin resistance produces higher total, free and bioavailable Testosterone along with lower SHBG (sex hormone binding Globulin)...all of which will lower E2 (estradiol) making breast growth impossible. Without knowing what your current situation (bmi, androgen levels, stress factors, diet, etc) is it's hard to offer meaningful advice.
