Don't let yourself be a prisoner of your past, free yourself to create another chapter in life

Do not accept the unacceptable, you are worth more! it is better to live honestly than accepting continuing unacceptable behaviour.One is you and your behaviour. When you are suffering from chronic disease, cancer is now a chronic disease. It matters the most to relatives emotionally and finances- needed. I honestly think the only reason they stay is they are afraid of how they will be judged by others for abandoning a sick person. I think its just time for some serious decisions to be made.  
Communication is key in these situations, but far too often the damage has already been done and you don't know why or how it happened. If you're not treated how you want to be treated, you'll constantly be going back and forth in your head about it.This disease is tough, but you're not alone. 
 .I can still function independently which helps a little, but all of those can't fully alleviate the daily stress caused by a dysfunctional relationship may it be a spouse or family. And in spite of the available support, I still find myself socially withdrawing, as I am losing the energy and motivation to seek that support out. But I know if I don't keep trying, things could get very dark emotionally. It often takes sheer willpower. dealing with cancer along with other physical problems makes deciding about emotionally charged issues like a domestic relationship even more difficult.What can I say I don't want to be a burden to anyone.
Let them feel what freedom is like outside of you. If your family truly loves you, will be back so it's up to you to make the most of your life: find alternatives, activities, support, sort things out for you and possibly put a more positive spin on your relationship and remove some of the blame you seem to be putting on yourself. 
Remember, "To have and to hold, from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, until death do us part"?I had a cloud hanging over my life for years- above the clouds in no time. and can find joy in things on my own.Find strength in yourself. There are always bad days, but there are also good ones. There is always someone worse off than you. I hope to I can find comfort and strength I needed within me.
