What can happen to someone who feels depressed

Suicide is because people don’t feel understood, loved or supported. People who have a mental illness don’t like to let it out just because of the stigma that people have around mental illness just others don’t see why somebody is sad all the time or; someone doesn’t want to do anything, maybe they are depressed or hurting and they don’t want to talk about it.. we all have down times so why do we think mental illness is just made up just so they can get out of something: NO THEY ARE HURTING! Suicides are happening because they feel like they can’t say anything about having a mental illness just because of the stigma, so they don’t tell us! Hiding it can lead to suicide!
