How have you overcome really old psychological injuries?

I was relentlessly bullied during adolescence because I’m gay. I’ve worked through much of the trauma and really do lead a peaceful life. However, I’m still bothered by some of the memories that are seared into my brain, and this stuff happened 3 decades ago.

Did you experience a hurt that took you many, many years to overcome? How did you work through it? What steps did you take?
