Don't feel bad most players your age suck at chess, it's a rare 13 year old that is any good, just keep playing and in a few years you'll see some real improvement. By the time you graduate high school you could be a strong player if you have any talent for the game.
As a retired teacher, I've played at least a thousand students over the years, only met a few 8th graders that played a competent game, but I ran into a lot of 12th graders that played very well.
Not everyone can be a chess prodigy, the most important thing is to enjoy the game.
