I'm new in nofap

Hello, I am new to nofap, I am 18 years old. I always have be very shy I am a chemistry student. I like chemistry because I have always thought that chemistry is the solution to everyday problems, even for PMO, as it has a chemical basis. Anyway, my greatest dream is to help people, and the best way to do it is by studying chemistry. Unlike other people, I did not choose my career for the money I can earn working. The best salary that people give me is when they say me "thank you" because it means that I did something good for someone, and with chemistry, I can not only help one person, but I can help an entire population. This is my dream. Sadly, I started viewing pornography at the age of thirteen, influenced by classmates at school. At first it was not serious, because my parents did not leave the house often, it took months for me to have the house alone. When I entered high school, the schedules of my whole family allowed me to be alone at home, so the situation got worse, overnight, my grade in school was decreasing. Nowadays I have been trying everything for 3 years to get rid of this curse, I did not go very well, because my intelligence had decreased, it took a year for me to start studying at the university, because I could not pass the entrance exam. I have realized that every day, PMO has taken away the desire to fulfill that beautiful dream that I described in the first paragraphs. That is why I am here, to fight PMO and continue to love life as I did when I was a child.
