There are no silver bullets for things like these, you really need change - but you are in a position where you are in a very demanding period of your life and you don't really have the resources to ease the burden. I am very sorry that you are going through that.
In terms of refreshing myself, sometimes I find when I am in stressful situations that I just need a bit of grounding, I remind myself of my situation, my objectives, and my direction. But also pay attention to that if something needs to be cut, then work on cutting it. There is also no shame in finishing things later, if you need to defer for a bit - do so
Sometimes you may need to bite the bullet and accept that this is a temporarily hard situation, and it's OK to feel like crap. You know your working towards a goal, but whether you think it's worth it or not that's up to your judgment. It's tough being ambitious unfortunately
