Perhaps the ECT could be a reset for you. It was for me. I'm definitely not the type that would use ECT very long-term. A normal series did seem to help make medications work better a second time around.

I'm sure you didn't mean it as thus, but I thought I'd add for others that the work with a therapist is not what really helps the most. It's the work we do ourselves, perhaps based on the direction or encouragement of a therapist. Just as medications can't always do the work for us.
