I do not believe that you are “insane.” Technically, insanity is a legal term and not a diagnosable condition.
I can’t answer the question of whether or not you are living a “normal” life. Only an in-person evaluation could provide a definitive answer to that question. However, you have provided enough information that I can offer general information.
It’s not uncommon for people to interact with fictional characters in their mind. As you noted, it is especially common among the youth. Sometimes these situations develop as a defense mechanism. Defense mechanisms are strategies used by the unconscious mind to protect oneself from painful emotions. They, however, can be costly. Much like a tourniquet, they provide temporary relief. If left in place too long, they can cause problems. Perhaps that’s what’s happening in your case.
Alternatively, it’s not clear from your letter that anything is wrong. Does it cause you severe distress or dysfunction in your social, professional or other areas in your life? If not, then there is likely no problem.
I wonder how similar your experiences are with that of a fiction writer. Perhaps the only difference between you and a fiction writer is that they record their conversations with characters in story form. What you’re calling “insanity” might actually be a literary gift. Have you considered fiction writing? You might be a natural.
If you’re worried, then it is advisable to meet with a mental health professional to determine if a problem is present. There may be nothing wrong but if so, a mental health professional can guide you in the right direction. Good luck and please take care.
