No, if you self admit you can still keep your clearance. At least at the Secret level. If you are admitted to a mental institution after a breakdown it might be a different story, but I don't know anyone like that. But getting counseling and being on antidepressants isn't an automatic disqualifier. And when I said decent human being, I left out the part mentioning that it helps if you have parents who are American citizens and aren't in a whole bunch of debt and don't have a bunch of foreign contacts. But I think you'd be surprised at how easy it is to get a clearance if your job requires it.
