Reset, Be Sensitive & Caring

So I informed DD and MM about the results. Unfortunately of course they will have to accept it. I observed 2 different reactions. Both reacted the same, i.e. have to accept it, but the motivation behind is quite different. One is without 'an eye for an eye' drive, one is with some sort of that. The one without I could clearly sense its outwardly dissapointment and sadness, and alot of motivation to recover, so to stay young and healthy, otherwise, for an old person, it would mean a heart breakdown and if not managed properly, surely will break down! For the other, I gathered and observe alot of justication for own actions, even to the part of his/her "wrong-doings" - justifying that even he/she would say no and does not care what others think. If they want to think otherwise, there's nothing he/she can do. Hence, he/she expects me to be that way too .. I should not expect anything and should just accept it the way he/she decides and it doesnt matter what I think.. Honestly, its easier to live life that way 'on the surface' and also its selfish and incosiderate because there's so much protection for his/her own self - afraid of getting hurt therefore applies such technique. Then I saw more .. observing the big picture.. their daughter to feel the same and they are treating their son the way their son have been treating them (which is now quite apparent to me since their son adopts the same thinking and treating the sister the same way!) and their son is treating them that way since they treat their parents the same way! I am soooooooooo tempted to treat them the same way too! Honestly, at this point, I want to take everything that I am giving now, for "why should I care", "I dont have to please you", "I don't have to change my plans for you" attitudes .. (that everyone is adopting?) - I could easily say, I cant afford, I dont really care what you think - if you want to think I dont love you coz I dont give you money its up to you - I am not giving anyway, .. but I cant do it - BS!!!! When all this is so clear to me now, its so disgusting! The chain reaction is so powerful, its coming to me! But I really have to break it on my part.. I can't change them but I am not going to be one of them. So what should I do ... reset, clean up the house inside me and be a sensitive and caring person.
