I know EXACTLY what you mean.
I so need a therapist.
"Does anybody else despise the weak like I do? Is it normal for me to not really want to change? Is change really necessary?"
1. Yes.
2. No.
3. Yes.*
* - Subject to change. I'm not even sure if it is possible to change.
If what you're saying is really true then you must carry a lot of stress. A kind of stress you build up passively which is fueled by pretty much every little thing that annoys you which in turn creates a great deal of hateful anger. When I was your age Z I used argue and flame online just to get rid of some of this anger and for awhile, it worked. Then I found myself in the same position that I was in in the beginning. Like you, I got my own figure of "weakness", my father and because of the way I think and feel about him and the weakness I see in other I've ended up in some pretty ****ed up situations as Vashti would know. She is like my online therapist. I've ended up in police stations and the hospital because of it and til this very day the anger is still there.
Like I said, I need a therapist.
