In case your diet is not up to par(too much sugary and fried stuff, say), you could try hiring a nutritionist especially given that you have $ for a psychiatrist. Not that diet/nutrition science is all that rigorous, but at least they could optimize your diet to the extent that you start feeling a bit better.

Intermittent fasting is another tool. And the most important one of them all - good night's sleep.
