Newbie here, am I cooked?

As the title says I'm newbie, trying to do my second muscovy run, the first one Poland did a blitzkrieg on me and now seems the Ottomans are trying. Their mil tech is better than mine so I'm not looking to engage them at the moment. Hungary has Lithuania on a PU and they are my allies. Any ideas what I should focus now? Thinking the only thing I can do is go east...
