spells? not really, you could try calming teas, or herbal remedies [i use St. John's Wort but check with your doctor before taking anything] aromatherapy might also help.
stress cannot really be wished away, it requires work on your part. what is causing the stress? figure out the trigger and try to lessen or resolve this situation. otherwise you can try a variety of methods to reduce stress, relaxing baths, exercise, taking time to focus on hobbies you enjoy, meditation, even journalling could help your stress levels.
