How is your sleep? I find that eating, exercising and sleeping are the base activities from which everything else follows. You mentioned the other two but not sleep.
You mentioned seeing a therapist, but have you taken your symptoms to a doctor? It is possible that your issues stem from a physical illness as opposed to a situation.
On the subject of practical advice, I suggest keeping a journal or diary of your moods and events of the day. I was able to use this to identify triggers that cause me to enter a depressive unproductive state so perhaps there is something that might help for you.
