Asking too many questions. Be treated.

My mom having nerve problem. She has a shock in her childhood days and she has taken treatment at early stage. Now she is alright except few problems. 1) She use to ask too many questions repeatedly which sometimes may not be relevant to the situation. 2) More devotional. Since she is too much involved in God, she will stay dating the whole day, she will think that she is keeping things clean by washing clothes too many times... Bcos of which she is getting health issues. She is 53 now. 3) Not giving importance to the wanted one (children marriage, future plans) and sometimes giving importance to very simple things like if one vessel got broken she will be most worried and scold everyone for that. Please suggest some solution for the problem which my mom has. Kindly advise whether this can be treated.
