I am sorry to hear about your school experience. Schools can destroy a kid's life if the bullies dont understand their limits. I didnt have any good memories of my childhood as well and dont miss my town or anything related to it. Sometimes I feel that I spent my life just suppressing my emotions which is affecting my health as well. But I believe that the future is going to be much better than the past.
I believe that roots are not important, but what matters is the community that we can happily belong to and be accepted in!
