Take some time to relax and take care of yourself. If you can take some time off, do something that relaxes you or makes you happy. Yoga, meditation and deep breathing exercises can help temporarily relieve stress and anxiety but you should still seek a therapist or counselor for further guidance.
Next Steps
I would recommend talking to a therapist or a counselor as soon as possible. If you are experiencing constant stress, it can affect your sleep and eating habits.
