Foggy brain, can't think, anxiety, suicidal... makes me wonder what is going on physiologically. I have most of these problems and many more. I would never look to a therapist to solve any of them, nor a psychiatrist. As for emotional support, I see nothing wrong with wanting this, and if therapy leaves you feeling bereft, because its a professional relationship and you are only getting little dollops of faux-caring, I hardly think you're to blame for feeling ill at ease with that.
