If you have ever mentioned you
are suicidal, and it gets into the TSA database, you

Realistically speaking everyone is depressed now and then, and sometimes, especially after a traumatic event, the depression may be severe and last quite a while. I would not be so quick to accept "treatment", to include drugs or psychotherapy. A few sessions with a psychologist may help.
