Welcome to the Community, let9it9rain. Do your parents know you are struggling? Do you trust them enough to show them a copy of your post? If you are going to deal with the problems you speak of, you likely will need professional help. To achieve a good result in treatment, you will have to be forthright and open with what you are dealing with.

For example, do you understand why you started creating this fantasy world at age 7? What happened that caused the misanthropy and the creation of the fantasies?

I am not a professional. Nonetheless, my suggestion is for you to first talk to your parents to see if they will schedule an appointment for you with a general practitioner. I think you should have a complete physical to find out if there are any somatic problems. You should then be referred to an appropriate professional for a psychological assessment.

Thereafter, a treatment plan may be formulated if treatment is indicated. If you do receive treatment, your treatment team should encourage asking questions so you may add your input, understand what the goals of treatment are and what is expected of you.

Good luck.
