I've been in a similar situation. There's nothing worth salvaging. It looks like your best option is to get out. Start looking for your next job immediately. It's easier to get hired when you're currently employed. Don't consider any counter-offers they might make. Leave quietly and professionally. As tempting as it might be to make a dramatic exit, there's no upside, in terms of your career. And take comfort in the fact that you'll probably one day look back on this as a valuable learning experience.
