I found this but I haven't used it:

myTherapynet.com
myTHERAPYnet.com provides an environment for licensed psychotherapists to conduct online psychotherapy and life coaching services. People are able to receive therapy in the form of real time chat, audio or video conferencing. A customer can book a 15, 25, or 50 minute session or can be connected with a therapist within 15 minutes and engage a session as long or as short as they would like.

Soidhonia also suggested this hotline number on the depression forum 1-800-273-TALK if you need somone to talk to. If that's not the Samaritans, there is always the Samaritans.
