Are most people suffering in a terrible way silently, or is it just me?

I suffer on a daily basis silently.Not many people know.Everyone think im a happy popular outgoing person.when in reality im misearable,suicidal almost at times, have little to no drive or hope. Alot of people bottle things up and people never know. Yet theres never a shortage of people there to cast judgement on situations and people they really know nothing about. Spare a thought for the person you p on the street even. A smile can make someones day seem alot easier. You dont know what's going on with them
