You don’t need to have “done” anything to just be. You can be loved for who you are regardless of what you’ve “achieved”. I’m so, so sorry to hear about your brother, and I wish you and your family the strength to keep going despite the pain.

I feel your loss having done similar for two brothers. Doing things is not what life is about. It is our relationships that matter. Focus on that. Was he a father? Husband/boyfriend? How about any neices/nephews? How was he with his friends or the rest of the family? Many funeral homes now have a questionnaire to help with this. for a school program I even had to write my son's obituary. They do make you think about those relationships. And although this is a horrific situation, learn from it. Not about going and doing Things, but become the friend/spouse/person who you want to be so you are remembered, how you want to be remembered. The thing is that the two can be very similar. focus on a good relationship to build on.

Start doing shit. I ought to be a life coach.

I wrote a eulogy for myself a while back - Just because I thought that for once it would be nice if the deceased had written their own eulogy. Only a braggart would focus on their “accomplishments”. In the end, it’s relationships that matter most - starting with your closest and moving out to your extended family and friends, etc… “Accomplishments” mostly count at the end for what they enabled you to do for those important to you. My own father was a good man and had a decent life - But at the end most people focused on how he had impacted his family. That’s not the stuff that makes the papers (except in the obituaries) but it’s how most people actually affect the world… By the way writing or delivering an obituary for a family member is one of the emotionally hardest things you are likely to ever do. You have my heartfelt condolences.
