Lets assume all your reads are correct. Best case, you are up against top set with no redraw, nut flush draw with none of your straigtening cards other than the A and what one can only assume is the Q high flush draw with none of your outs (which would be highly unlikely). In that case, you have about 20% equity.

In a more likely scenario, where the button has flush and straight outs, you are down to 10% equity or so.

It is quite possible that in this scenario you only have 1 or 2 outs that would scoop the pot for you. This is not an entertaining prospect.
