Late night thoughts for no one, but which I which need saying

I've started a habit of reflexively saying I'm a bad human. Saying it was reflex and I thought was there to only shield myself from other people thinking that before I was able to say it

But a friend called me on itm asked me what makes me bad. And I had no answer. I actually think I'm a good person, but I just. kept. on. saying. it. Realised that by bad I might mean not productive. But the words we use about ourselves shape reality
