Baby witch needing advice - energy protection

Hi there!
I’m a baby witch ~ 2 years into lightly studying/practicing. I mostly do tarot, basic rituals/spells that mostly do with cleansing, and astrology. I work at a job that deals with a lot of different energies all the time (server/bartender, often serving over 100 people in one shift) I’ve recently been doing some research on energy protection and clearing and how someone can unintentionally mess with your vibe/send bad vibes your way. I was wondering if there’s a ritual, spell or anything you might recommend to protect my energy, and keep negative vibes at bay? My big three are cancer, pieces, Sagittarius, so I’m very emotional and empathic, often being very affected by energies whether I like it or not 😅

Thank you so much for your help!
