As an aside, it is important to note your own role in your sister's health. Clearly you care so much about her, and that can have healing impact too!
Here are some ways you can continue to be helpful for your sister.
- I believe there are medical, physical, and emotional ways you can help.
- we've discussed the medical, but the others:
- From an emotional perspective, believe it or not, patience and understanding, loving kindness and compassion, are all vital aspects for any human healing. People who feel sympathy and love, or notice their environment is smiling and happy and uplifting are much more likely to share these feelings of positivity and energy than their opposites. There are many anecdotes around the hospital and in the public at large, where laughter, kindness, and love have brought health where it could not have come without.
- Physically, it sounds like you believe your sister has the appropriate support systems (physical, intellectual, emotional) available to him, and my impression is that you believe your sister has the cognitive capacity to seek these resources out if she so chose. While some may believe in more aggressive treatment strategies than I do, I believe greatly in a positive human spirit, and I believe in the power of positive motivation and reinforcement, and less so in the power of forceful or negative encouragement. These are matters that are easier said than done, I am aware, but nevertheless, I think the carrot serves better than the stick (or the annoying nag or threat, etc etc). Perhaps you could find activities that you can share with her? Fun board games, or exercise activities? Could you reconnect some of her friends or acquaintances to join in the motivational effort with her? Perhaps trips to a park or enjoyable activity from time to time? A change of scenery can often bring a change of heart.
