Am i crazy!!! or normal?

when i see videos of the mentally ill, i dont think like most ppl like ''omg! there crazy!!'' i'm more like ''omg!! that must being terrifying!!!'' and when most ppl would see someone say something like ''someone cutting themself'' instead of thinking '' there emo *******" i think "i wonder what happened? are they ok? they must be so sad.." i'm starting to think i have some sorta mental disease.. (i'm scared!!) what do you think? am i normal after all?? am i just empathetic?? i also have many addictions.. like cutting, s, picking skin, biting nails and i have problems with shyness, constant ual thoughts, anxiety when i'm alone/ away from the computer... i also notice i get short obsessions like for a week i cant get my mind off a singer then the next week i obsess over trying to write a book (these r just examples).. if i am 'crazy' can i be cured?? please dont lie i'm seriously afraid!!
