maybe you should be affected in such a way that you care for them but affecting you as a whole wouldn't be nice. i think you must learn how to accept the things happen around you and move on. Give your self a good life to live. If your parents didn't make it, then don't do the same mistake like what they did, think of it as a lesson in life that you must learn. it is also right if you seek help form a counselor or a therapist to help you understand more yourself and help you how to cope up with this situation.
