Mourning your own is consuming the karma, the emotion the energy. Ignoring it and entertaining it with the others is ignoring it, you understood the opposite.
However, nobody told you to do something or whatever but did give you advice. You are free to do as you see fit, such as drinking like a fool or whatever.
Yes you can be judged in these harder times of yours as well, and there are good and bad ways of dealing with this. And this can only be known by you.
In the end, after such a situation in your life, you still are not exempt from life's dealings. Nobody pauses time or whatever, and the empathy people express is also very organic to your situation.
Being with no parents, now without a sister does make you either extremely strong or opposite. You have to choose which one. Be a man, and do your duty to yourself and deceased family members.
Exerting this strong reaction within yourself unto others is pointless and fruitless. If you were for example, to glorify these feelings of rebellion in working for money or whatever, you'd have a lot of success. Etc.
As a note on this, for people who experience the same in life. The answer is not an empathic moon energy, as the tragedy in itself needs a lot of disciplinary action to refuse stupid outcomes out of these things. A strong masculine presence can help. Everyone has a friends such as so or whatever can get advice from such people.
Normally in men this presence of masculine spirit is awakened in tragic times, but it cannot be always perfected or on the right direction.
