Ignoring the drama in this thread:
I don't typically recommend a protective type guardian breed, ESPECIALLY such a powerful molosser, to anyone who has any kind of anxiety, social or otherwise. Mental state passes quickly from a handler to a dog, and certain breeds (usually the smarter, more one-person type dogs) pick it up faster, and a molosser with any kind of instability without a VERY experienced handler is going to become very dangerous very quickly. People with anxiety sometimes do look towards these breeds for protection and to feel "safer" but honestly, any large dog is going to do just as good of a job dissuading unwanted company, and nobody should be getting a dog like this for protection without YEARS of experience in handling them for other purposes.
That said, I don't think nobody with anxiety is capable of handling a dog like a dogo or corso - lots of people on this thread do so. But before you look into a breed like this, I think you need to be able to function (and do some comfortably) normally in social settings like clubs, classes, and public to socialize your puppy.
I've only met one Dogo, and from what I can tell, he was EXTREMELY watered dog. He was an apartment dog, and let people approach and pet him quite calmly in public, so I'm not sure that's the norm. However, I've known a few corsos.
All I can say is go meet some. Email local breeders and say you're interested in learning more about the breed, can you come and visit. Try to find a show, and especially if interested in bitework or PP, a club to visit many times before deciding what breed to bring home. ACD experience isn't going to TOUCH preparing you to own a dogo or even a corso. There's a very good reason you don't see these dogs walking down the street all the time. They are way too much for most people, including incredibly dog savvy people, to handle. They're not even all that common in bite sports, because even for people who participate in those sports and lead that lifestyles, they are an awful lot of dog.
The reasons you're listing in this thread make me believe you might be better suited to a breed like a rottie, GSD, or maybe some kind of less "intense" mastiff like an English or Bullmastiff.
