Who ever said you couldn't? I believe in you Swim!! SWIMMY SWIMMY SWIMMY!!! Sorry if this is a troll post but not trying to!! I'm just saying other peoples opinions don't matter, if you let them get to you then what they say is true!
Let me tell you a story my soccer coach always tells me that helps!!

"There's a horse and it falls in a well! So when the farmer discovers he decides to bury it with dirt bc he knows he can't lift it up out! So everytime they threw some dirt down the horse would SHAKE IT OFF and STEP UP!! An eventually got out!!"

My point by this is that whatever people through at you that is negative, shake it off and step up, prove them wrong!!

GL and hope you do good in the tourney Swim!!
