My sincere condolences. I lost a bipolar friend to suicide 15 years ago and it hurt hard. We met in a kickboxing class in San Francisco. A friend found my name in her address book and called to tell me what happened. I still think about her. She was an athletic and beautiful lesbian and once let me sleep with her when I had nowhere to go and she woke up in the middle of the night prodding my chest and wondering why I didn't have breasts. I attended her wedding. I wish that I had been around her in her final days; I may have been able to offer some support.
She survives in our memories.
