If you are a real nun in the FPMT then you can get money from the Lama Yeshe Sangha Fund. If you really don’t have money, this is one way to manage if you cannot find external sponsors. If you work for a Dharma center, the center might be able to help you. If you stay with Tibetan nuns, most nunneries have someone who speaks English.

Some nuns have more money, some have less. Don’t be in too much of a panic in life. Life is short, you can die at any time, so you need to practice Dharma every second. Keep in your mind bodhicitta and guru devotion, to benefit others. Your mom, who you think is selfish, is the most practical guru, who helps you have realizations, develop patience, love, compassion, and thought transformation. She is the one who brings you to enlightenment the quickest by letting you put into practice what you learn.
