Fired from job I love

I got fired from a job I really love because of “performance issues” and when I asked my boss, she mentioned it was my “lack of attention to detail” that led to her decision. It really feels like a huge blow because I was really passionate for what I was doing , and I had been TRYING my hardest to make sure I reread and double/triple check my work. I hate having to implement all of these extra steps , that for other people are unnecessary. I hate having ADHD so much. I officially got diagnosed a year ago and its been a huge process just learning about the condition and how to cope. The world is really unfair to us. I just wanted to get this off my chest.
