The other side of anxiety is depression. Live with anxiety for long enough and it will morph into depression.

Do you like walking or running? Either one is great and will help you convert stress into endorphins that will make you feel good. Any kind of physical activity.

Do something that makes you concentrate on something outside your own mind like gardening or wood work or needlework.....Any kind of hobby that takes the focus of what is inside your head. Painting?

If you like drawing (No talent needed at all for this to work) Get a pencil, pen any medium really, just get your emotions out onto the paper. I like using crayons because they feel good in my hand. You don't start of with any kind of picture. Sometimes just breath and let yours emotions be shown. It could be pages and pages of black scribble - If you are angry choose a color that expresses that. If you are sad (Blue or Grey) use them. Use what you want. No body is going to critique it. U can just draw shapes. I had a couple of art therapy lessons and it is amazing how we can express emotions this way.

Mine isnt art...... It looks infantile really, but sometimes it just makes me feel........

Be your own artist.
