Kombat Judo

What fighting style is right for me?

I would like to learn some fighting style but I don’t know what I want to learn. I am not interested in wrestling or judo since they require so much strength and I honestly am not the strongest person in the world. Does anyone still practice the ancient fighting styles like snake, monkey, tiger, eagle, dragon, and all that other mortal kombat stuff? I need something simple like that. I would like to learn a russian fighting style since that makes up most of my heritage, but most of them are pretty much just like wrestling. I dont have any money, but if you could just tell me some fighting styles that would work for me and that I can learn for free, online, that would be awesome.
I am like 5’5″-ish and I weigh about 130 lbs. Oh and thanks for your answers. Some of them are very nice.
I would also let you know that I am only thirteen so I may get stronger later in my life, but I still dont like judo and all that crap.

Why fight the “little man” syndrome?
If you are small accept it….
