Initials... it's not as uncommon as you think... but this is a forum for the more 'normal' forms of attraction, particularly within only one species.
I would suggest looking for forums that pertain more to paraphilias (which is what zoophilia is). There's bound to be other people like yourself who are looking for support and answers.
It's good that you want help... but this isn't the right kind of forum, since few people here (if any) can relate to you... and none are trained to help in something quite like this.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
- James Allen
