I go normally because I need my therapist to know me when I'm stable. That way s/he knows my baseline thought paterns and my baseline opinions of my life, s/he can see when I'm slipping (either high or low) and help me correct it before it gets out of hand. Lastly for me this is a person I have to trust with my life they need to know all the little details of my life to advocate best for me when I can't. 48 hours (*X years) isn't not very long to know someone that you have to trust with your life.
