We all go thro a time of not liking at least something about ourselves or situations in our life and it feels horrible, even depressing. It doesn't help even the most caring person to be told "well there is someone worse off than you". Whether you know the person or not, clearly they are reaching out for help which is good because they are showing at least a little that they care enough for themselves to not want to feel the way they do. Talking it out how they feel should be encouraged and getting another persons perspective can help and sometimes make them feel less alone and the 'problem' feel less overwhelming. The worst thing to do is brush them off when they want to open up. Its ok if you don't know how to deal with their situation because there are a lot of professionals out there to help. When I was 13 my friend committed suicide, I had no idea how he was feeling because he never said anything and seemed to act 'normal'. I've always asked how people are feeling ever since, if I know them or not because no one should feel so horrible and alone to take their life.
