shows that you do not see yourself in as positive a light as others do, at Psych Central for instance.

You count in my book. You are an important person that I want to reach out to. I am not selling my time, I give it away freely in the hope it will make a difference with one person.

Self-esteem is how we view ourselves. Maybe that could be something to bring up in your work n social therapy. Our own self esteem is the most important part of relating to others. Without it we are going to have a good time relating as equals.
