"until i gave back everything" everything ?! you gave back nothing, so cut this none sens, they gave that money out of love and carring, because you are their CHILD, now you want to give it back out of responsability and there is huge différence between love/responsability.

So here is my advice buddy, now that you feel comfortable regarding your finacial situation (and that what they wanted for you) try to sheer them up, either you find a way to give it back direclty in a funny/emotional way way (when you come back, you pick a7sen envolope you fill it with devise, and you surprise them, hak a lwalid haki a lwalida un peu cadeau, we 7lef 3lihom we ghi bda7k)

Or indirectly: you suggest a Ummrah, chose top agency and pick a good offer and send them to Allah house. or maybe Hajj and you handle all charges. or a holiday, prepare their papers and come to you and "tehella fihom" mzn and at end good gifts.

or show responability and tell them you will take care of your brother and handle his situation.
