My sister has autism

Hello to everyone this first post, I am very happy to be with you in the forum, in fact I have my sister 15 years old and she is autistic and still has not spoken, we live in Morocco and especially in the village and here they do not care about autistic patients, and our difficult living situation does not allow us to treat her outside the country, we suffer because I did not depend on herself yet for example do not know how to wear the toilet and this is a troublesome suffer, recently Someone suggested to us a special center for people with autism and he takes care of them, but unfortunately it is very expensive than $500 a month, which is difficult for us, so what do you think about this and what is the solution?
