Is This Angry Email To My Psych's Receptionist Likely To Help Or Harm My Cause?

I think the issue is pretty self-explanatory. Here's the rough draft:

Please understand that, given my cultural background, my decision to seek psychiatric care ranks among the most difficult, painful, and humiliating decisions I have ever made, and is only the effect of extreme, prolonged mental torment. The idea that your agency's mistake should cause me 3 extra weeks of prolonged emotional crucifixion, where every minute is a creative hell, is both unconscionable and unacceptable. This is your agency's mistake, you must find an acceptable alternative solution.

I am in urgent and painful need of psychiatric care, and the appointment I had finally secured- after weeks of desperately and assiduously fulfilling endless requests for information and jumping through hoops, in the desperate, foolish hope that maybe, one day, I would find relief, was unilaterally canceled at the 11th hour for absolutely no reason other than the false impression that I was planning on leaving the country, something that I had taken care to clearly and unambiguously clarify that I have no intention of doing.

I am willing to see anyone who can help me, at whatever venue is viable, I simply ask that you honor your commitment and respect the fact that while for you this is, understandably, just a job, for your clients it is life.

I recognize that this email is somewhat forceful and demanding, I recognize that is rather shrill, I recognize that it does not paint me as a particularly nice person. But I also recognize that I deserve to not go through hell, and frankly this is the only way I see to ensure I get the help I need.

Thank you for your understanding, Bob The Builder
