Welcome to PC. I believe you will find a lot of support and understanding here.
I'm so sorry for what you've endured. I understand the guilt of feeling like you weren't there for your brother, but people make their own choices. It wasn't your fault.
Do you have a therapist that you can go to, to help you through all of this?
Please take good care.
