I have worked with several spirits who have taken their own life and were earthbound. One of which was attached to my friend and was bringing her down with his sorrows, to the point that she was ready to go.
What I have found is that many things they say you will be sent to hell for just aren't true. I only awakened last year and I have already lost count of how many spirits I have crossed over, many of which lived less than savory lives. And yet with a little push they were all able to be forgiven by god and the angels. I do think being earth-bound for some time is the punishment they receive. This is just my experience however.
