Just have to think what i/anyone commiting suicide would put their family through, parents, siblings, partners, kids etc... its a very selfish act, but then again, if things are so bad someone is in a frame of mind in which they could go through with it then i guess its not an issue.

Id say its a mental illness, unfortunately either un-detected or covered over by other issues in the persons life.

Terrible thing for any friend or family to have to go through.
