There are so many ways to use your flower.
In my darkest moments, I would create a rose in my imagination and put it in front of me with the face of the flower facing my heart area. I would ask it to take my pain and sadness. I would allow all my pain and sorrows to pour into this rose. I would then blow this rose up and feel the blessings rain down on me.
This is not a one and done, I had to do it a lot, but over time the layers of my anguish were released from me.

Create a giant lotus around your house where you are living.

Another thing you could do which you may find hard is to bless your brother. Not out loud, but in your mind. And with heart intention, not mindlessly. You can say "bless you" or "May you be blessed", whichever feels more natural to you. You may find this could be transformative to the whole household. Your brother is in dire need of blessings, he is in pain.

I like "may you be blessed" when I don't want to feel like a hypocrite blessing a jerk, but they are still being blessed. When you bless another, you are also blessing yourself.
