I know it's a few months in the future, but I wonder if your big trip will help things become clearer--having that much distance from the situation and seeing so many other options in front of you. I know when I spent a while in asia, it was a lot easier for me to let go of things I had been clinging to that weren't helping me anymore when I got back. In fact, it put me in a place where it was like I HAD to let go of those things in order to survive. But it came very gently--I wasn't even trying to solve or address those issues when I was gone. Just like, once I was in a different situation in Asia, the thought of going back to certain parts of my old life in the US became intolerable. So I made a bunch of big bold decisions when I returned. It might happen to you too! But I'm not sure you want to wait until you get back to make big changes.
