It's hard to really understand what it must be to live through such a tragedy, so I'm not sure how relevant my suggestions will be.
But I would do three things (some of which I see mentioned in several post below):
1. download as much as you can – wikipedia, stackexchange (e.g. https://archive.org/download/stackexchange), openstreetmap; possibly, set up a local wifi router to allow others to access these and, if you keep it technical, it might be that this will enable you to get in touch with others with similar needs, which should keep you learning together as much as possible
2. if the conditions allow, try and get your hands on StarLink. Getting a dish and router might be problematic. But if you like diy and assuming you can actually sign up to it, it should be possible to self-build a connection kit using spare parts and an ordinary sat dish.
...which brings me to...
3. consider getting into ham radio. This, once again, depends on the situation in the country, and whether licensing is an option or not. But, providing you can and that you have electricity, this could get you in touch with others, who will usually be techies and may be able to also answer coding questions (although this is a willingly long stretch). And, albeit at very low speed, Internet via ham radio is itself a possibility, e.g. https://spectrum.ieee.org/build-a-longdistance-data-network-...
All the best to you, and I hope the situation improves quickly!
