That's unfair. Most of the mental health related comments are in direct response to someone else bringing it up.
The title of the post pins down the problem (OP describes themselves as "unhireable"), but in the post it is everybodies fault but their own and they fail to disclose why they think from the perspecitve of a company they are unhireable. I don't see any issue with making mistakes. But not learning from them to protect a mythical image you painted of yourself and your abilities is not only a problem but also a wasted chance that will come back to haunt you till you address it.
If I would be in the position of having spoofed a phone number to call a superior and loose a job, I would be ashamed or at least re-examine the state of mind and perspective that lead me to the dubious conclusion that this would be a good idea. The fact that OP seems to file that under "daring, but could have worked" rather than "this was totally inappropriate, how could I have ever thought this would be??" is what promts those mental health related comments.
What OP needs to get hireable is a reality check that leads to a lasting change of mind. This can be incredibly hard and painful, but if OP is clever they will know that this needs to be addressed and go through with it. The worst thing OP can do now, is gloss over that particular aspect of this thread and not address the discrepancy between their self image and what their words, decisions and actions communicate. The worst thing so to speak is to continue lying to themselves.
Know thyself and all that.
Are you saying that in "professional" situations (job applications, or even asking for advice on HN), you need to hide your struggles and present an image of a flawless worker who handles all situations in stride, even though you can't live up to it because of mental/life struggles, depression, and the looming prospect of homelessness?

I'm not an executive, however I am a team lead. If you found some way to contact me directly, unsolicited, on my work phone or email, I would blacklist you. Especially if you had circumvented some security measure in order to do so, let alone spoofing what we can only assume is the phone number of another employee? The time and attention of these professionals is valuable. Procurement process exists to prevent executives at prominent, successful companies being interrupted in such an inappropriate manner.
You sound like you need to adjust your attitude. From your perspective it may seem that you're an underappreciated talent just waiting for someone to give them a chance. From the perspective of a recruiter or hiring manager you look like a serious liability. Especially if you're looking to make a leap upwards into your career's 'next step', it's extremely imperative that you demonstrate your ability to succeed in simpler, entry-level positions.
Your writing is terrible, and unprofessional. If you can't get through this thread without discussing your mental health problems that's a serious red flag.
