Important Descisions and Depression Difficulties

I'm having a really hard time with an important descision and I'm not entirely sure why. I'm currently in a certificate program that will make me eligeable for the master's program I was planning on entering. But I'm not sure if it's still what I want. I still enjoy the subject (Egyptology), but I've been feeling unmotivated and burned out on the subject lately, and this isn't the first time I've been that way. I've also been considering teaching English overseas, but now that I have an interview, I'm losing interest in that too. Looking over the job description, it seems like a very people-dense job, and being an introvert, it just seems overwhelming. I have a wide variety of interests, any one of which could have been a career, but between long-term depression, school costs, and a narcissistic mother, I'm in my 30's with very little to show for my work career wise, and some of the paths I was interested in either are closed or would be a lot more difficult now. On top of that, I really need to move away from my narcissistic relatives, and needing to save for an oversees move would make that almost impossible since I would need to buy a car. I also need a career that would support me, both short term and long term.

So now, I just feel stuck in this descision. I'm not sure which interest are genuinely mine and which ones my mother pushed me into. I know for a fact that my interest in ancient Egypt is at least partially a coping mechanism, and I don't know if it'll last past healing. I also don't know how much of this confusion is depression-induced apathy and how much is genuinely changing interests. I don't want to make such an important descision too hastily since I don't feel like I'm in a good place to make it, but I could lose even more opportunities if I put it off too long. My mood's been ok overall, but I've been so anxious and easily frusterated that I haven't been able to start anything home-based, either. I just keep going in circles and I'm not sure how to stop. Any advice?
