I did the same too, swaying in and out of Dharma, one day I want to do more, the next day I just want to quit. Walk away and never look back no matter what happens.
Surrendering to my laziness, ignorance, pride, ego, etc. People around me couldn't understand my feelings for Buddhism, how much I eagerly want to learn more but they were always telling me that I am wasting my time doing something so 'holy'. They break me and make me slip further because I believe them. And then there are so called Dharma friends who criticize, gossip, backstab, favoritism, etc. So I totally understand how the nun feels except I don't hold 300 vows and wear a robe.
Her Guru understood the difficulties she was going through and He let her go out into the world to learn that it is worse out there. People go to Dharma centers to learn and becoming a nun is truly someone whom I respect as they give up so much, they may not be perfect now but they are still learning and becoming better.
The Rinpoche she met gave her hints and advice for her to wear her robes again and encouraging her. It doesn't matter what color her robes are but her practice to become more understanding, tolerant, forgiving towards people is what matters. And running the orphanage, teaching all the love, kindness, etc are the best ways to raise them.
I am so happy there is a happy ending to her story. Thank you!
