I love the article, Erin.
One thing I do want to mention - suicide, and the suffering that leads to suicide, is, in my experience, almost always caused by negative entities that are in at least a partially possessing relationship with the person taking their own life.
As human Souls, we don't take our own life - there is a greater part of us that knows and understands the consequences that Erin outlined so beautifully. But negativity can attach to a degree that the part of us that is here in the physical loses all connection with their Higher Self. Choicelessness, hopelessness (and, yes, lots of mental disorders) and the ability to abdicate our responsibility here is usually due to negative entity interference.
This, by the way, does not make us victims of negativity, because we choose to engage with these entities. Usually we do so unconsciously without recognizing the consequences, but we're still responsible.
Anyway, I've done readings from time to time for Souls that have committed suicide, and have found those Souls in the same states that Erin and Lallymac described - some have successfully crossed with the help of guides, some are stuck in the astrals or the earth plane. Cause was always possession energy by negative entities.
Just another angle to consider.
