Should i take up squash?

im 13 and i want to take up a sport. i dont usually like sports, but my local leisure centure is starting courses and i think it might be worth going. kinda nervous though cos id be in a room full of strangers. im not exactly sporty hehe (unless you count walking) and i think my biggest reason against it is that ill mess up in look like a retard and not have a mate there to laugh it off with. ive looked it up (cos ive never heared of or played it) and it seems interesting. should i go?
