wow i thought i had it good with my straight

I was in a freeroll tourney and this is my bad beat.
I was short stack.
So my hand was Ac 5c

The flop came out as:
9c 2d Qc

He raised I called hoping another club would come.

The turn:
5h

nothing that helps... he raised half the pot.. me being a donk
at the time called.

The river:
8c

I was so happy, i knew... or thought i had it i mean i didn't think he would actually have something that would beat me. A straight wouldn't do cause my flush would
beat his straight. That's when i made my move and went all in.

BIG MISTAKE
My opponents hand:
10c Jc

He had it. That stupid straight flush i couldn't believe it. I was so pissed, im surprised I didn't break my computer. lol
Well that was my bad beat...
can you beatt that??
