Welcome isloth!
A video game addiction is nothing to be ashamed of. Some people have alcohol, others have drugs. Can go on for a while: sex, food, pain, gambling, perfection, porn and so on. Addiction is everywhere. Everyone in their life has been tempted in one shape or form. Some people are less or more likely to develop on addiction as well. In the end, be proud you are making steps to get better.
Be cautious not to want to move too fast; take it easy. Baby-steps. You can have a fallback if you move too fast. Hear that a lot from people who want results fast and failing because of it. It takes time so please take your time.
Hope you feel comfortable here and I wish you much luck in making all these big steps. Doing great!
