Oh hunny I'm so sorry...it must be heartbreaking. There is nothing that you did or didn't do. Sounds like she was in alot of emotional pain and couldn't see a way out. That makes me sad...I'm so sorry for yr loss. My best friend is very ill and I know she only has a few months but at least I know ahead of time. You didn't get that opportunity. Just try and remember how much she impacted yr life and remember her for who she was/is. Just take good care of yrself.we're all here for you.
