I agree with Burning Aroma.

• Aunt dying
• Sister nasty
• Friend tried to commit suicide

Rather than lazy, it seems life is battering you and the feelings of helplessness, worthlessness and laziness are bruises. Under those circumstances I would most probably shut down.

Please let the feelings run themselves out and take care of yourself the best you can. When safe and ready, you can devote some energy to your aunt and friend.
