I am very sorry for your loss.
Suicide is a very.. taboo subject even today, but I witnessed my best friend mourn for a friend of hers who committed suicide.

I do not believe, if you commit suicide 'you go to hell' In fact, I dont believe in hell.

Her spirit guides, would have helped her with the transition - and for whatever reason she done it for. They will be helping her heal.

If it helps, talk to her. The biggest question is 'why'. But not everyone opens up and the most unexpected people could commit suicide.

I hope this helps somehow.

Stay strong
