I know something about sacrifice (my father sacrificed a lot and in time i also did something similar) so i hope my suggestions are helpful to you.
1) First off, it is your duty to help and look after your Mother/Grandmother/Sister as long as possible. You are all in it together and each have to be clear about their responsibilities and contributions so that your family as a whole is stable. Best case is relatives/friends help out and worst case is you are on your own. The latter is what you need to prepare for.
2) Second, set your Mental Attitudes right. Build up Fortitude and dial down Expectations and Wants drastically. Your mantra should be "a bird in hand is worth two in the bush" until you achieve a financial sweet spot. The immediate future is going to be very difficult and unless and until you "keep it together" things are apt to blowup. Be prepared to do a lot of sacrifices.
3) Third, Financial planning and stability is everything at this stage. You and your Mother absolutely need to keep your jobs and bring in some steady income. Grandma can take care of household chores along with your Sister. No money should be "wasted" on anything frivolous. Everybody should know and be asked to deliver on their specific Responsibilities.
4) Fourth, i foresee your Sister as a source of possible problems in the near future. All of you need to sit down with her and make her realize the precariousness of your current situation and how she needs to "grow up" now. No unnecessary expenses and if possible she too needs to get a job asap and help out the family. Only after you have reached a financial sweet spot should she (and anybody else) be allowed to indulge in their "Dreams".
Good Luck!
