You/Your Mother (the two people who are earning now) need to be Pragmatic and very strict when it comes to Money/Finance.

So have that chat with everybody in the family (and in particular, with your Sister) as a group so that everybody understands the gravity of the situation and can deliver on their Responsibilities while keeping their spirits up. If you all stick together, you can definitely make it to a better place in Life.
Also since you seem to be in the EU check whether there are any social safety net plans that your family can qualify for. This can be a huge boost to future success.
