I can tell you that saying what you want to say to the world, at least in my experience, doesn't work. The world doesn't care how you feel or who you really are. That's why I myself hide behind the nice guy. If you've got a support structure that consists of "emotional vampires" then it's that much worse because they only want the positives.

The best thing I can offer is to find a "soft spot to land". Someone you can go to that supports you and offers you an ear.

Oh, and I saw in your signature that you're on Cymbalta and can't afford it. Try switching to Venlafaxine. It's an SSNRI like Cymbalta, but you can get it generic for a fraction of the cost. I was on Cymbalta and couldn't afford it and Venlafaxine has worked just as well for me at literally 10% of the cost.
