I can offer some general insights on the matter.
It is essential to remember that individuals react differently to stress, and it is not uncommon for people to experience physical or mental health issues due to stressful situations. While stress can be a contributing factor to certain health conditions, it is rarely caused by a single event or person. Stress is usually the result of a combination of factors, including life circumstances, coping mechanisms, and personal health.
If your mother is experiencing health issues like PMR (Polymyalgia Rheumatica) and she attributes it to the stress caused by your arrest, it is crucial to approach the situation with empathy and understanding. She might be going through a difficult time and expressing her emotions in this way.
However, it is important to recognize that responsibility for someone's health conditions cannot be solely attributed to one person or event. Stressful situations affect people differently, and many other factors could be contributing to your mother's health issues.
If you and your mother have open communication, it might be helpful to have a calm and honest conversation about how both of you are feeling. Sometimes, discussing concerns and emotions openly can lead to better understanding and help resolve conflicts.
Remember that seeking professional support from a counselor, therapist, or family mediator can also be beneficial in navigating difficult family situations and emotions.
Please keep in mind that my advice is based on general information, and it is not a substitute for professional medical or psychological advice. If your mother's health condition is a concern, it's essential to encourage her to seek advice and treatment from qualified healthcare professionals.
