(Note: I'm a psychology grad student, my undergrad work was in neuroscience and psychology.)

Psychiatrists (in America at least) are usually too busy to do much psychotherapy. When they do, get ready to pay big time. It just isn't worth their extremely valuable time and in any case, it isn't their specialty.

You don't want to see a clinical psychologist because they treat people with diagnosable psych. disorders. You may have melancholic depression, but it sounds like you just have extreme akrasia issues. If you go to a psychiatrist first, they'll likely just try to give you worthless SSRIs.
