Bad or unlucky play?

[Shorty35]

6 players laft; blinds at 50/100 (increasing next hand; 15 min intervals). folded to LAG in cutoff with stack of approx. 1750, who calls for 100. I am in SB with 99 and stack of 600. I have VERY tight image, having had only one playable hand so far, which went the wrong way. BB has about same stack as me, and is also tight. I raise all-in. BB calls all-in, CU folds. BB shows JJ, which holds up.

Did I pull the trigger too fast/too hard here; or just run into the wrong cards with the correct play? I "knew" I would get a call if I committed T300 or less, so I figured it was all in or nothing.
