You were never bad nasty person. And you did not deliberately treat people badly to cause harm. Not at all.

You were a struggling person. Not to say you don’t struggle now, we all do. But those were growing pains, struggling with looking for your place in the world and looking for ways to live your life. You were also figuring out your mental health. During those struggles people might say and do some harsh things.

In addition you were younger. Many most wonderful people were holly terror in teenager years and above. I’d say it’s normal.

Also this is mostly mental health forum so if people expect everyone to be on the best behavior at all times they shouldn’t probably be on this forum. Not the right forum

You are an inspiration and a role model of growth and perseverance and ability for a great reflection and insight.
