You know what my problem is?

Everything needs to be perfect.
I sometimes get told I’m too critical of others, but I’m far more critical of myself. I had an oral exam yesterday which went great. Only my written didn’t and that’s the only thing I can think about now. I can’t enjoy the good things I achieve because I spend most of my time blaming myself that I didn’t do it perfect. That I didn’t push myself. I have a pathological need to excell in everything I do. I have an absurd fear of failure, especially when it comes to academics. I know it’s okay to take a hit. To get a setback every once in a while. I know that’s how you learn things. I’m just not sure how I can convince my brain of that.
