Sad to hear about your challenging situation.

It leaves me wondering, "selling all my devices" is a good solution.

If you need to communicate by mobile for job or social reasons,

You may keep just a prepaid card and one device to remain at least reachable.

Just wondering, will you use an old Nokia "dumbphone" while they are still cheap and that costs hardly an electricity for being standby?

Don't sell too much! Don't end up trading a fishing rod for one sandwich.

Fingers crossed that you can build up some resilience towards an easier future.
