You may feel responsible, but can you change anything? It sounds like the answer is no.

You may love it too much to let go - you feel like you would lose a part of yourself if you leave. But if you stay and watch the thing you love being dragged through the mud day after day, is that going to be better, or worse? I suspect worse.

I suspect that you can't do anything to help. I suspect that you need to get out, because staying is going to destroy you. Staying (even at the price of being destroyed) to save others is noble. Staying and being unable to do anything to help isn't noble - just unwise.
