When should I chant mantras for financial anxiety and career uncertainty?

My name is Priyanka Sharma. I was born on 12th June 1995 at 3:50 PM in Jaipur. I have been very anxious about my career and money recently. I get into a state of worry about the bills, my money invested, and my success in the job all the time. One of the suggestions given to me was to perform the Lakshmi Gayatri Mantra daily. I really want to know when and for how long the chanting should be done so that my financial worries go away.
