My depressive phases are very long 1+ years. Very profound. I am without motivation, also, when depressed. I am more frozen in limbo during those times. I've more recently been helped with the addition of Abilify. Abilify and Adderall help me some. (BPII)
(My first seriously depressive phase was 30+ years ago. We can get through it, although it presents quite a challenge... time and time again.)
I hope you recover soon.
