Informal letter

Dear Mom:
 Hi mom, I´m not happy about writing this letter but I have to tell you my story.
 It begins like this: I was researching in my laboratory one day, when I had an idea. My idea was to create a potion that separates the people into two different parts : the good part and the bad part. When I finished creating the potion I drank it and transformed into an evil person that killed a lot of people.When I realized about that, I stopped drinking the potion, but the transformations didn´t stop so I can´t control it.
 And now I´m here in my room. I send you this letter because I want you to know I am going to commit suicide. I only wanted to tell you bye.
                                                        Bye for ever

Dr Jekill, your dear son
