It can be challenging to see our loved ones suffer and this can often have a significant impact on us as well. It is good to see that you are recognizing the fact that this has had an impact on you and are concerned about your sister as well. I would suggest that you seek regular therapy on the platform from one of our many qualified experts. This will allow you to discuss not only some of the challenges and thoughts you are dealing with but you can also understand how to help your sister better.
Hope this helps.
