What if this is my calling?

I've had to make a difficult decision as well, but not to the extent that I would give up my life for. It is not right that the parents would resort to this kind of emotional/mental abuse. Of all the siblings you are their last hope? They should have realized by now that out of all the children you are the only one remaining. It is understandable that you are worried about your dad's high blood pressure but if it becomes worse or better, it is still your dad's responsibility to take care of himself. His wife/your mother is there (for sickness & in health). Have you told your parents how you felt? What have your siblings have to say about your staying/leaving? Can you stay with a sibling & see what happens to your parents? If you cannot tell them, then write to them. Let them know how you feel. I don't think they would want you to commit suicide either.
