Not sure if you ever read Eckhart Tolle's "The Power of Now" or "The New Earth", Steve, but maybe give them a gander, if you are so inclined.

There are some amazing revelations in those two books that might help you with how you are feeling right now. Not every single word of the books will resonate, mind you, but a lot of it may help you to understand why you are feeling the way that you are right now. It definitely helped me.

AS said the rest - that is one very intelligent person right there. Keep out of your fleeting emotions- they will pass as they always do.

Keep strong, man - you got this.
