This is a "great" learning experience that sucks when you are experiencing it but you can (try to) comfort yourself with that you are learning a lesson now while you are in your PhD program. The more you learn now, the better off you will be later.

At least, that is what I keep telling myself. And I counter that with "If it doesn't kill me or put me in an institution first." or "better off doesn't mean much when there's so, so much else that is wrong." (The pessimistic side has subsided since I accepted the "real" job offer. And while I'm at it, can I discourage you from doing a postdoc unless you really really know what you are after? In fact I hope you have a really good idea of what you're going for with the PhD, and that it isn't a tenure track faculty position, because there are way more people who are very well qualified than there are jobs.)

Sorry, that was a digression. Anyway, this is an interesting conversation.

I agree, it sounds like this is a bad environment, and if you can extricate yourself sooner than later it would be best. Before you fall victim to the politics that are playing out. Trust me, it sucks to get kicked out of a lab.
