> I've been drinking all kinds of clamming teas, supplements, trying to change my diet, walk more, etc...

One thing that helped me to calm down during a very difficult part of my life (and I'm not saying this will be a complete solution, but a partial one) was massages and isolation baths.

There's something about being physically relaxed that seems to transfer emotionally.

Best of luck.
