Really?? How irresponsible are you to want death when your family at that condition.
The first step for your situation is. Start with helping yourself, try meditate for 10-15 minute after you calm, star listing what you have, no matter how small it is, than see what you can improve(example have roof for sleep, have time for internet acess, etc) than find how to leverage what you have for your situation.
Example, you stay at home have internet acess etc, than you can make a post in crwodfunding site for your brother illness, do some publication, learn how to publicize it, how to make the crowdfunding suceed.
Remember no on will help you, if you doesn't want to help yourself. When you start helping yourself, and struggle, than you will start see the possibility. I suggest you to read journey section the pinned one.
