Life In 19x19

Hi everybody,
In the game above, I made a pretty terrible mistake at
After that the cutting stones are dead and I think I've already lost. But it's been awhile since I had a chance to play so I at least try to turn the table if possible. It didn't go well enough I suppose.
In your opinion, should I continue playing after ? Looking back I think I should have resigned after this.

If you think the game is still playable, I'd really appreciate pointer (directions) for things I should have made in later moves. But of course comment for any part of the game is welcome

Black has indeed lost and should resign. Good way to think about it.
Playing another game would be more to the point than dragging this one out.
