I am very sorry that you are faced with this challenging situation. I would encourage you to speak to your father. Make him aware of your fears about your mother. He may also be unaware of the fact that your mother continues to have symptoms despite being on medication. This is a sign that she may need her medication adjusted. It may also mean that she is not taking her medication.
Is there an adult family member or family friend with whom you can stay? Moving may not be an option but ideally it would be best for you to be removed from the chaotic home environment. Having a strong, supportive person in your life is important. It helps you to feel safe and protected in your home. It is difficult to relax in an unpredictable living environment.
If you believe that your mother is a threat to herself or to others, then it is imperative to call the authorities or the local mental health crisis team. I fully understand and appreciate how difficult making that call might be but safety is paramount. If she is a danger to herself or to others, the hospital can protect her. It may not be the ideal option but it is the most effective option.
Finally, you and your father should consider contacting the National Alliance on Mental Illness (NAMI). NAMI has support groups for individuals who have family members with mental illnesses. They have support groups in virtually every city across the country. NAMI support group members are dealing with issues that are very similar to yours. Having that support may assist your family in dealing with this situation. Please don’t hesitate to write again if you have additional questions or concerns.
