Phineas & Ferb Theory

THE PHINEAS AND FERB THEORY (http://anitasnotebook.com/2013/11/phineas-and-ferb-the-true-story-and-dark-theory-behind-the-show.html)

'The Phineas And Ferb Theory says that (like Angelica in The Rugrats Theory) the real Candace has lost her mind due to bad things happening in her life.

The theory says that Phineas was her little brother and he was bullied a lot in school because the other kids thought he was too nerdy. One day a bully punched Phineas in the head really hard and it killed him.
That day changed Candace forever.

Candace couldn’t deal with Phineas’ death so she built an imaginary world where he was still alive and playing with her other brother Ferb. Ferb has a disability and can’t talk or do much, but she imagines him and Phineas going on great adventures together.
The real reason why her mother can’t see the things that Phineas and Ferb build is that, well, they simply aren’t there. And the more Candace tries to convince her mother the more crazy she becomes.

The villain of the show Dr. Doofenshmirtz is actually Candace’s psychologist who she’s been seeing twice a week.  It started to put a strain on the family to try and pay for all these expensive doctor visits though. In desperation her mother had an idea to write down all the fantastical stories Candace was telling her and try to sell it to Disney as a show, and it worked.' 

I've seen and heard loads of different theories about Disney shows having underlined messages about mental health, for example apparently in Winnie the Pooh each character represents a different mental issues:

• Winnie the Pooh: He has an eating disorder, and perhaps attention deficit disorder aka A.D.D where it is very hard to focus.
• Piglet: It is believed that he suffers from Generalized Anxiety Disorder. The theory states that he may have suffered from an injury that crippled his self-esteem, and that his stuttering problem most likely developed from said injury.
• Owl: Dyslexia and Short-Term Memory Loss. Even though he's shown as being exceptionally bright, it's shown that he has trouble reading. An example would be in Pooh's Grand Adventure when he mistook the word school for "skull." Also Owl tends to forget things as quickly as he says them.
• Tigger: He suffers from Attention Deficit Hyperactivity Disorder. Tigger's always seen bouncing and can never stay in one place for a long period of time. 
• Kanga : Social Anxiety Disorder. She is very overprotective of her son, and she would never let her son make his own decisions because of her overprotectiveness.
• Roo : Autism Spectrum Disorder. He lacks awareness of danger and has a strange attachment to sitting in his mother's pouch.
• Rabbit: Rabbit suffers from Obsessive compulsive disorder (OCD). He is very orderly and obsessive, and the theory also questions his sexual orientation due to his feminine behavior.
• Eeyore: Not surprisingly, he suffers from Depressive Disorder. He always has a bleak outlook on life, and never feels any positive emotions like happiness and excitement.
• Christopher Robin: Lastly, Christopher Robin himself suffers from Schizophrenia.

They are mostly fan fictions that are discussed in online forums but they could perhaps be true!!
