FIVE WAYS TO FIGHT DEPRESSION
If you feel depressed, it's best to do something about it — depression doesn't just go away on its own. In addition to getting help from a doctor or therapist, here are 5 things you can do to feel better.
1. Take a 15- to 30-minute brisk walk every day — or dance, jog, or bike if you prefer. People who are depressed may not feel much like being active. But make yourself do it anyway (ask a friend to exercise with you if you need to be motivated). Once you get in the exercise habit, it won't take long to notice a difference in your mood.
2. Depression can affect appetite. One person may not feel like eating at all, but another might overeat. If depression has affected your eating, you'll need to be extra mindful of getting the right nourishment. Proper nutrition can influence a person's mood and energy. So eat plenty of fruits and vegetables and get regular meals (even if you don't feel hungry, try to eat something light, like a piece of fruit, to keep you going).
3. Try to identify any situations that have contributed to your depression. When you know what's got you feeling blue and why, talk about it with a caring friend. Talking is a way to release the feelings and to receive some understanding. If there's no one to tell, pouring your heart out to a journal works just as well. Once you air out these thoughts and feelings, turn your attention to something positive.
4. With depression, a person's creativity and sense of fun may seem blocked. Take time to play with a friend or a pet, or do something funny for yourself. Find something to laugh about —- a funny movie, perhaps. Laughter helps lighten your mood.
5. Depression affects a person's thoughts, making everything seem dismal, negative, and hopeless. If depression has you noticing only the negative, make an effort to notice the good things in life. Try to notice one thing, then try to think of one more. Consider your strengths, gifts, or blessings. Most of all, don't forget to be patient with yourself. Depression takes time to heal.
To fight depression one should:
A. be highly motivated
В. consult a good psychiatrist
C. remember to eat healthily
D. try different kinds of physical activities
E. look on the bright side
F. try to make as many friends as possible
G. not forget to humour oneself
H. try to find someone to share his/her problems with.
