Struggling to sit and watch my sister as end of life approaches

Hi, 

I feel your pain. I really do. I lost my beautiful wife in July, I stayed by her side for the 3 nights she slept. I was hoping she would wake up, but she never did. I’m missing her so much. Just be there for her, talk to her all the time your there. Tell her how much you love her, and tell her that it’s ok to let go. I did. And I really believe she heard me. My only real blessing is that my lovely Rosemary had no pain either. She just fell asleep and never woke up. It’s going to be very hard, but take each day one at a time. I’ll be honest with you, it’s going to be very hard, but you must carry on as best you can, she would want that. 
You will never know how strong you are, until being strong is all you have. 
Just let her know your there and that you love her very much. XX 

I am so very sorry for the loss of your wife, i tell my sister everytime i see her and leave her that i love her, sometimes i just sit holding her hand. I hope you have plenty of people around you to help you through this very sad time. Thank you for all your advice i will take it on board. I hope you are managing to find some comfort in this very sad time and thank you so much for taking the time to reply to my post xx
