Since my teens when bullying, living in fear of other kids and being singled out were regular, I had withdrew from a lot of growing up and failed to reach my potential in school and in college rarely interacted with other students and stagnated doing IT courses, hanging around alone during breaks.
Now at mid 30s few things have changed irrevocably, my body had aged yet my mind has been stuck for 15 years. I do not take rejection and scorn well, see everyone around me as potential threats and didn't count on the tremendous obstacles, expectations and fluctuating emotions transitioning into an adult.
Maybe I am immature, ill developed and a poor excuse for an adult. Living with constant shame of being behind everyone else and never really being acknowledged or accepted, just existing.
