Hello, poster child here. I am terrible that way.
I have improved when it comes to time with people I really look up to or complete strangers, but I still over-analyze other relationships- those with my friends and family. Probably because over the past few years I've made huge mistakes with those closest to me.
What caused my improvements with my nervousness around people I admire? To that I credit my college professor, I'll call her Mary. I adored her. I wanted to grow up to be this amazing woman, and would get nervous, jittery, and do stupid stuff in her presence. You know what happened to Mary? She ended up having a nervous breakdown and was hospitalized for mental health issues. She missed two quarters from work. Leave it to me to look up to and want to be someone on the verge of a complete nervous breakdown. Well guess what? I've succeeded. I'm just like her.
