Help my mom pay for our education

We are a family of 3.My mom works really hard for our education but her salary is never enough for both of us,me and my sister.We live in Greece and we pay for our apartment monthly because we do not own one.She never has time or money for herself and it makes me really sad.So i really want her to get some help in paying our education bills.I am an economics student at a greek university and my sister is in high school,i am currently looking for a job,but it is really hard since salaries here are very little.She has to repay 8000euros in the bank,because our dad left her many loans.I would appreciate your help which is very much needed during this time.She has been through a lot for us and i want her to be happy finally.
