A fraud, you say? That’s called imposters syndrome. I suffered big time from it too.
But you went to school and passed the required classes. You’re not a fraud.
I fucked up a bunch in my early years too, until I was diagnosed with a severe form of MTHFR. Once I got on the right meds, my lifelong brainfog went away, and I could suddenly do all the tasks I found so difficult to do prior, including study. Went back to school. Now I design Substations.
I also get the feeling sometimes that I’ve faked my way into the job I have. But no. I went to school and passed the classes. I’m supposed to be here.
