Have you ever dealt with Someone that has depression? If so how?
What do you mean "dealt with". Do you mean try and support them and get them the help they need? Be supportive of them and try and check up on them even though it may be hard to be around them?
The way you phrased that question makes it seem like you want to know how you "make them better" or "snap them out of it". Depression is difficult and depending on what is causing it may be short term or something they struggle with long term. It can be difficult to see friends go through it but there is no one answer or solution that will work. The best thing to do is to again try and be a friend, listen, and encourage them to get help especially if you think they are going to be a danger to themselves or others.
