Anxiety is defined as "a state of uneasiness and apprehension, as about future uncertainties". Dealing with anxiety is different for each person, and what works for some may not work for others.
Some of the things that I utilize to deal with my anxiety are:
Meditation: Mediation can be very relaxing. By focusing on one's inner-self and letting the problems, uncertainties and fears slip out of focus you can allow for a clearer solution to be found. Sometimes simply stepping away from your problems and calming down can help you see solutions.
Exercise: Exercise can be very invigorating. Anxiety can leave you feeling depressed and run-down. Exercise boosts endorphins in your body, leaving you feeling refreshed, happier and less anxious.
Yoga: Yoga is a form of exercise that does not involve impact. Yoga is more a series of fluid movements and stretches than vigorous exercise. The fluidity of yoga is very invigorating, yet it is relaxing and calming while still producing endorphins in your system.
Talking: Sometimes talking about the things that are making you feel anxious can really help lighten the burden of the anxiety. Find someone that you trust to talk to. By vocalizing your anxiety, you may find that you are less anxious.
Relaxing: By indulging in whatever relaxes you the most - a bubble bath, a walk in the park, watching a movie - you can allow your anxiety to pass by not focusing on it and instead enjoying your relaxing time. Detaching yourself from your problems and fears, even briefly, can help you cope with anxiety.
