Chasing a draw with a lot of action

[phillydilly]

I've seen this situation a few times, chasing a draw, where each call in itself is correct, but it just seems like poor play. the only thing i may have done differently is push the turn (i dont think i have enough to push the flop). But the way this hand is playing out, i seem to have very little, if any, fold equity, so i feel by calling i save myself an extra $10 or so by just calling and folding the river unimproved.
thoughts on this hand?
apologies if its routine
