Well, First of - i agree with Paraclete completely.

Second - for a while, it helped me with my suicidal feelings. I held strong to my therapist. Then he figured it out when i told him i adored him and he got a little bit nasty...even thought he said it was NOT a psychological trick and he was sorry for hurting my feelings...i...well... the illusion is sort of broken now....but you see -i collected myself right now and decided to move on...IDK how to explain. He told me that it would be hard for me and i could call him - but a part of me (since i do have parts) got hurt form his way too harsh way of saying "you can NOT touch me!!" (never intended to!) and i did not call him this week. Collected myself together and moved on with my REAL goal. I just know he is not my final destination and i will get over him although the process is disappointing and sad.

Still...well to your question - i think that it is ALWAYS both sides. Both good and bad. Like anything. It is all about using the benefits and learning to handle the disadvantages.
