I have never really belonged to forums before, so bare with me....
I know how you feel as I have been feeling the same. I know mine has to do with the situation I am in and its too bad that people don't consider mental abuse from a narcissist as actual abuse. So I feel so stuck.
The responses already in this thread are true, but I understand how it is hard to believe and hard to apply to your own life. I have the same trouble.
It is also harder when in fact you have no one. When I say no one, I mean not one person that you can trust and rely on.
Its good you at least found and forum to let some weight off of your shoulders and you should get the number for a crisis line in your area which is what I am about to do.
I think the best medicine is to reach out to those who understand what your going through and stay in touch with those people.
I truly hope that things only get better for you and for the rest of us who are dealing with these demons.
