I have not gotten a diagnostic from a professional yet but I'm definitely planning to go see one to increase my chance of recovery. Most hoarders haven't seen a doctor for many years like me and it's believed to be related to our lack of organizational skills.
I 'm sure that I have this problem though because unlike other mental disorders this one actually materialize in your own living environment. I have watched many hours of experts PhD of the subject and that's how I learned how to start my own cognitive behavioral therapy.
