When you ask someone to shrug off with their depression, you simply make their condition less trivial and ignore their pain. For people fighting depression, cheering up is not quite easy. So, be a bit kinder to them.
If someone opens up to you regarding their suicidal thoughts, take them seriously before it’s too late. And please don’t make a joke of it because it’s hurtful and insensitive. If you find this is something a lot that I am asking for, please try and walk a mile in their shoe for a day. Trust me you will realize. You will know that the shoes are so heavy that you will fall before you even take a step.
Be patient, be thoughtful, be kind, be human!
