Very poignant and deep introspection there. I find that I put tremendous weight on the acceptances and/or rejections I will receive. It feels as if my self worth is determined by them, by a decision from a group of anonymous strangers sitting in some conference room somewhere. What do these strangers know about my worth? I am more than my GRE score, my statement of purpose, my letters of recommendation. Why do I let myself be enslaved by their mythical mastery?
It's pathetic, and I'm angry I feel this way.
I try to play hypothetical thought experiments: if I were accepted by my dream school today, would I be a different person tomorrow? Somehow, I think so. If I were rejected? I'd be a loser.
Of course, this is all false. I'm the same person today as I am tomorrow.
