I agree with UKFF, kick boxing would be a great base. If there is none local what about western boxing?
Failing that, any training; karate, tkd, tang soo do, kempo, kung fu etc,any training that teaches you how to strike, body movement etc and help keep you fit would be a good base.
If there are no striking arts near you, consider a grappling art like ju jitsu, judo, bjj, aikido etc. Any of these will also teach you body movement and control and would be a great addition to a striking art.
Learning without an instructor is virtually impossible if you have no experience.
Good luck finding a good place to train. Get your parents to check out the instructor's qualifications/insurance/first aid certificates etc. before you begin.
