Is this normal

I should start by giving some general backround information.
Through out most of middle school, I was on enough medication to kill a horse. I have had numerous diagnoses, though nearly all were given to me while on medication.
Recently I've stopped taking nearly all of the medication I was on, and I definitely feel different.
My most recent diagnosis, and my only diagnosis while off medication was post traumatic stress from living in a neglectful and abusive home as a child.
Anyways, I thought that would help with your idea of why I am feeling how I currently am.

I'm always very apathetic, I don't care too much about anything anymore. Sometimes the boredom gets to me.
What I've been doing lately to help with this is relationships.
For the first couple of days I love it, its very entertaining. But after that, I'm just very apathetic again. Bored with who ever it was I was with, and wanting to move on to something more entertaining.
It's not only relationships that I do this in, though. It's friendships, housing, schooling/work, how I look, etc.
I am constantly making drastic changes in my surroundings in an attempt to cure this never ending apathy, and nothing works.
Sometimes its as if I've lost any touch with the world.
I don't like this apathetic feeling, and nothing I do makes it go away. I just get myself caught in bad situations.

What does this sound like to you?
And no, I am not depressed. I have been on nearly every anti depressant there is, and all they do is make me manic.

I need a label for what's going on with this so I can fix it.
