How to get rid of acne and small white bumps present on my face for the past 3.5 years?

Hello doctor,

I am a 23-year-old female with acne for the past 3.5 years. It comes and goes. I have a habit of popping my acne, so I have many craters on my face. Along with big pus-filled pimples, I also get small white bumps on my face. When I squeeze them between my nails, white stuff comes out, which is sometimes solid. In an effort to solve my acne problem, I wash my face with harsh soaps very frequently. This causes my skin to become dry. I have had success with solving my acne problem by washing my face with hard soaps once. But now, it does not seem to be helping. My skin texture feels extremely weird. It is dry and dull. Not very dry, but moderately dry. And just weird in general. Please help. Also, I have very poor eating habits. Sometimes I do not eat for a whole day. I do not drink water either. Even when I eat, it is always junk.
