This is a question to discuss with your parents. As the article states, there are many benefits to private schools and I am not sure I understand what you mean by wanting to invest more in yourself and focus on yourself. You and your parents need to decide together what school is best for you based on what school options are available to you and what your ultimate goals are. If staying at private school is the decision made, look into whether the school allows dual enrollment or look into what volunteer opportunities there are. What activities does the school offer? Are you involved and making the most of the opportunities you have? What are the reasons for wanting to move to a public school? Is there something this setting provides that your current school does not. If so, make a list of your reasons and present them to your parents.
