Interest Lost

I will never know why, I lose interest in almost everything I like or do. I can't ever have hobbies, I can't ever watch TV series. I can't get into much of anything even friendships. I want friends, I want hobbies but I can't seem to be arsed or have interest to stick with anything. I don't know why I've always been this way, I'm always quick to move from thing to thing or move on to nothing. I just wish I could feel passionate about stuff but I just can't seem to.
