Yup, their lack of empathy and views on manipulating people makes them interesting to me though. The fact they can do certain things without a second thought that most people can't even bring themselves to think about themselves doing is so fascinating to me. And no, what little I know regarding psychology I learned from just being curious. It's more of a loose hobby for me. I'm more interested in meteorology than psychology too so I don't know how many psychology courses I'll take/be able to take once I reach college.
I also have that.. situation? predicament? ,,,thing? not quite sure what to call it but my family's not emotionally open either. Showing any emotion (especially strong emotion) never went over well and usually resulted in being told I was overreacting or throwing a tantrum. I don't think I confided in someone until 9th grade when my depression was at it's pique and one internet friend begged me to tell her. She got (and still occasionally gets) the brunt of my venting which while I feel very bad about I'm also incredibly grateful for. She's currently prepping for college though so if I have a bad day my only option is to write it down in what by definition is probably considered a diary though I just like to refer to it as the thing that keeps me sane when I need it to haha
