A child living in an abusive family with no way out and/or being bullied may feel extremely anxious and alone and attention seek to obtain the love they are not getting at home, either by cutting or fighting or being a drama queen or getting obsessive over things or
looking for an older partner to take of her.
A rape victim or person from a sexually abusive
relationship may have a more hidden type of depression where they plan to kill themselves but pretend to be happy and normal
on the outside around those closest to them following the rape. A survivor of rape, several years on might be more open about his or her feelings in regard to this and show more obvious signs of their depression.
Someone who has
experienced an abortion as the result of sexual abuse might have a long term alienation and confusion over their life and a more subtle form of ongoing depression they don't really talk about.
A lot of people with depression are considered selfish and self-centred, which is an ignorant way of looking at that person. If someone has horrendous problems, of course they're going to be depressed over them.
