First, take yourself out to the health food store or the bath shop and splurge on some essential oils that have antidepressant properties. Try bergamont, neroli, chamomile, geranium or rose. You can also make a bath salt blend.
Here's a recipe for "Uplifting Bath Salts" from Eden Foods:
1/2 cup Sea Salt
8 drops pure essential lavender oil
4 drops pure essential rosemary oil
4 drops pure essential geranium oil
6 drops pure essential lemon oil
Bring your essential oil or bath salts into the bathroom, along with inspiring, soothing music or a guided meditation CD. Of course, be sure to keep electric plugs away from the water. Start the music or meditation tape even before you run the bath.
Arrange top-quality chocolate or another special "treat" item within reach of the tub. Make sure that your treat is something that will leave you feeling wonderful--not sluggish or hyper.
Immerse yourself, refilling the warm water as you wish. Let the music flow through you, enjoy the candlelight, make a ritual of eating the chocolate or treat.
Wrap yourself in the robe and move into a new, more positive space.
