I'm not a professional, but I do work in the video streaming field where we get a lot of reports. Generally we direct them to various suicidal hotlines, websites, and provide a chart to follow to gauge the severity.

So say you want to be the GGG, and help someone and talk to them - at some point, even me now for example, I have felt like I wanted to die, what what you want to look out for is if someone has a plan of action, a time, a date. etc etc.

Good professionals, should someone decide to get help, will usually start with a low dosage of a medication and do weekly follow ups to see how you are feeling. Then stress the importance of diet, getting outside, being active, cleaning your room...GETTING A ROUTINE. They let you know that ALL medications with depression are for a crutch to help you, not heal you.

Sorry for being serious. Source again, my job deals with a lot of streamers even dealing with this, and my family has a history of mild/manic/bipolar depression and anxiety.
