You can't get rid of the symptoms. Absolutely no way. I spent a very long time trying (wow, what a trip it's been!) You have to get rid of the problems BEHIND the symptoms.
For example, say that underneath it all you have some issues with your family. Or the way you interact with people. Or something else that is a normal every day issue...
But those things, in order to fix, would require YOU to do silly things like be embarassed, lose your pride, lose your sense of vengeance, etc.
NO, you think. I WOULD RATHER NEVER TALK TO THAT PERSON AGAIN.
(this is just an example of a problem. your "problems" could be something else)
But basically because you are SO unwilling to see something about yourself, your brain is producting scary symptoms. You've basically told your brain "I don't want to think about [real life problem]" So your brain kept bringing it up and bringing it up and was eventually like "Okay. You dont' have to think about that problem. But in order for me to keep you from EVER thinking about it I'm going to create some new obsessions and symptoms for you. That way you will be so goddamned busy trying to fix these feelings of being unreal or dead, that you will never HAVE to focus on that silly little real life problem again." and you're like "Well why do you have to replace the real life problem wtih symptoms? Can't I just totally blank it out?"
No. Your brain cannot get over or rid of major unresolved issues. You're "avoiding the reality" of having to face these things, and so your brain kind of makes a metaphor of it...since you refuse to face reality, then your brain is like "ok, everything is not real". Because you're contradicting yourself somehow.
Go to therapy, talk about the stuff going on in your life. It's the only way out.
(Also, i have a feeling this is where the "special" feeling comes from..."I'm too smart/beautiful/intelligent/busy" to think about those real life problems...just means you're really afraid of them)
