Do I have synesthesia?

Hey guys. Ever since I can remember, I have always given different numbers personality traits in my head.
Here are some examples: 5 - nice and optimistic 7 - depressed 8 - somewhat nice 9 - douchebag who everyone hates 10 - really cool and everyone likes it

And the list goes on through every number. I have been taking psychology for three years and have read about synesthesia alot but I never never put 2 and 2 (no pun intended) together until very recently. Its not a big deal if I do have it, but I am very curious.
