My dear....let me tell you one fact.....family problem will never cease...after solving one another surfaces.. You are too young to be carrying such weight in form of family burden.
I know you can't see your loved one's living in abject poverty and keep mute but how long will this carry on.....you are a young man...yet to be married...if this continues how can you combine your extended family needs with your own family?

My Advice

If you can teach them how to catch fish.....setting up something for them to manage and be earning money.
Prepare yourself for another phase of your life called marriage..... "It 's not a child's play"
Please take care of your health....Remember nobody will do it for you.....

Get Well soon.
