How can i teach myself how to fight?

Sorry, but the short and true answer is that you can't really teach yourself how to fight. It is unfortunate that there are no schools nearby, but it is just the reality of the situation. Learning how to punch and kick is not fighting, it is like someone handing you the keys to a car and saying "Drive" when you have never learned how to do it or even operate a vehicle. Learning to fight/defend yourself is how to employ techniques effectively, not just the body mechanics of how to execute the techniques - mimicking body movement is just dancing, and you need context and instruction to turn those techniques into something useful. You could be the best puncher in the world, but still be a terrible fighter. You cannot learn to fight from videos or books, that is a simple fact. At best you might be able to mimic some techniques, and at worst you can delude yourself into thinking that that is sufficient to defend yourself which could lead you into a dangerous situation. The best strategy would be to think critically about how you can avoid situations which could get you into a fight, or even what you could do to get out of it.
