Unfortunately, some of my colleagues know about my depression. I have at times become suicidal and when you work in a middle school; other staff can be more aware and have assisted with keeping me safe. Sometimes, that is a blessing. Other times, it just makes me feel more flawed and inadequate.
Today is one of the days I just hide in my office and hope that no one realizes my current frame of mind.
As for telling colleagues or friends, I find that I tend to be cautious. I don't want to be viewed as "flawed or mentally fragile". Only my closest friends are aware enough to read me...
