What are some positive ways to deal with stress?

Many. Other than consulting a therapist, consider exercise, a healthy diet, decrease stimulants, massage, meditation, relaxation exercises, and especially dropping stressful thoughts. Stress is not only a matter of the situation, but your perception and thoughts about the situation.
Stay active. Exercise is a great way to relieve stress. Your body releases endorphins during exercise, which can help you feel calm. If you exercise 30 - 60 minutes a day, your stress levels can improve. When stressed, take 5 slow, deep breaths with your eyes closed, then roll your shoulders forward 5 times, then back 5 times. This will slow your heart rate and release tension in your neck and shoulders.
