You should not give up on cures. You say you have tried all meds, but there is quantity of details to consider. Not only which meds, but also in which pattern, in which combinations, for how much time. Was your pdoc really good, really good on your particular disorder? Experince is vital with mood disorders as there are no charts.
The same applies for psychotherapy, to find the right person is DIFFICULT.
I just mean: keep trying by all means, because I'm afraid that it doesn't pass by itself, and it doesn't get better with time passing on.

I wish you the best of luck
