So, we all know that grad school demands so much of our time and energy that it is impossible to get everything done. You have to balance course work, research, writing, and TA responsibilities like an olympic juggler, continually shift your focus from one thing to another (something always suffers), and try to keep your sanity in the process. It's a constant strain on your self-confidence and spirit. So, when you get those compliments or small victories, it means so much. You savor them. You write the compliments on a post-it note, save the nice e-mails, and relish the positive feedback. This is the honeymoon phase of the relationship; the calm before the storm.
Then, just when you start to actually feel good about yourself for a moment, when you think, 'Yeah, I can do this... I do have something to contribute... I deserve to be here," academia bitch slaps you. And, you're back to feeling like something your professors stepped in. Academia won't allow you to start feeling good about yourself. Academia puts you in your place. Academia is an abusive relationship.
Sorry to vent. I thought it was better to do it here than on Facebook, where I might regret it later.
Feel free to vent, too!
