You have classic signs of depression. Perhaps major depression.

The worst part of depression is that it clouds normal thought processes. That's probably why you can't perform as you once did.

Find a way to see a psychiatrist you feel comfortable around. Go with a family or friend if that helps get you over the hump.

So many high achievers I know go through this. You're not alone, and with proper help you'll get through it, and be stronger too.
