Saint to ask help from to deal with mother affected by schizophrenia

Hi, can someone suggest which Saint to ask for help in regards to dealing with my schizophrenic mother who is in debt and I want her to leave me alone (not pulling me into her problems, stop trying to force me to be hee caregiver, be more cooperative in receiving help).

Researching I found as a suggestion the combo of Saint Dymphna for her mental health and Saint Joseph for her debts.
