For about 3 years now I've have not cared about almost anything that has happened in my entire life. Even the most shocking experiences and images barely even phase me and the only reason I was able to work up enough concern to post this is because it has caused problems with my friends, family, and schoolwork. I used to be very passionate about alot of subjects but now I don't feel anything not anger, or sadness or hapiness, emotionally I'm constantly blank. Is there an actual cause for this?
