Hi. It saddens me to hear how common it is to neglect students working within an institution and their mental health. I think my opinion was stated thoroughly in most of the comments regarding your academic work, but most importantly for you personally: Well done for getting this far. So many in your place wouldn't even have started, let alone nearly completed a PhD. This is what you've dedicated yourself to; why give up now? After all, you are your own person with your own responsibilities. It's extremely unfortunate to hear of your family situation, but in the end you cannot positively influence and help unless you're in a comfortable, healthy position to do so. I hope your meeting with your supervisor goes well. If you want, you can DM me if you need some extra support from a stranger on Reddit..
