Crazy: reclaiming or just insensitive?

I have always thought that one has the right to identify with any term he or she wishes. Sometimes I can identify with the term "crazy". On my site I use it right in the name of my blog. That was a choice mainly because I know that there will be some insensitive jackass who thinks it is funny to send hate mail (Bitter? Moi?) and I wanted to claim that word as my own before someone tried to use it against me. Plus, I think it is a great way of standing firm in solidarity with myself, giving myself the credit I am due for what I have gone through and continue to deal with. (its a weird way of doing it but it works for me)
So while this is my choice, as it is the choice of all individuals, I think it is important to ask "why do we identify with those terms?"
There is part of me that knows that I am not 'normal' (see post below for my thoughts on the word "normal") and therefore feel as if I am crazy: I act and think different have different emotional needs (read: I do not have the 'normal' thoughts and moods). But why can I not just see myself as 'different'. I guess I have learned that it is very negative to be abnormal; crazy becomes the term used to denote different AND bad.
I guess what I am trying to say is: while I use and can identity with the term 'crazy' in a positive and motivating way, there remains the part of me that uses it against myself because of the internalized stigma of mental illness I feel from society.
