There are a number of crystals (that you can buy in jewellery form) that may well help.
Amber - has strong connections with the earth and is a grounding stone for higher energies. It's a powerful healer and cleanser that draws disease from the body and promotes tissue revitalization. It cleans the environment and the chakras. It absorbs negative energies and transmutes them into positive forces. A powerful protector. Psychologically Amber brings stability to life but also motivates, and can help to counteract depressive tendencies. It promotes a positive mental state bringing balance and patience. It should be worn for prolonged periods especially on the wrist or throat.
Citrine - is a powerful cleanser and regenerator. Carrying the power of the sun it is a very beneficial stone. It is warming and energizing and one of the crystals that never needs cleansing. It absorbs, transmutes, dissipates and grounds negative energy. It raises self-esteem and self-confidence and removes destructive tendencies. It helps you to develop a positive attitude and to look forward optimistically. It is excellent for overcoming depression, fears and phobias, promoting inner calm. Wear on fingers or throat in contact with the skin.
Moonstone - a stone of 'new beginnings', strongly connected to the moon. Its most powerful effect is that of calming the emotions. It is a very feminine stone. It soothes emotional instability and stress, and stabilizes the emotions. It provides deep emotional healing. It is supposed to be very balancing of the hormonal system. Wear as a ring or place on the appropriate body part.
Women may need to remove Moonstone at full moon.
Now it depends on how airy fairy you want to be but you should let the crystal *choose* you - ie. buy them in person, take your time, touch them, feel them, be open to being drawn to a particular stone.
Personally I would then cleanse the stone before wearing. Again depending on how airy fairy you want to be there are a number of ways you can do this.
Water cleansing - can be held under running water or immersed in the sea or in salt water. As you do so, hold the intention that all negativity will be washed away and the crystal reenergized.
Sun/Moon - placing the crystal in the light of the sun or the moon reenergizes the crystal as long as they are not ones that will fade in the sun (citrine fades).
You can smudge crystals or pass them through the light from a candle. You can also visualize them surrounded by light which purifies and reenergizes them.
Basically however you choose to do this you need to use visualisation techniques/meditation, positive intention. (you will find a lot of information on line if you want to investigate further).
Aromatherapy wise - Sweet Orange and Geranium essential oil blend is FABULOUS for emotional and hormonal balancing. Sweet Orange is uplifting, anti-depressant and generally just lovely. The two together are very special. Neals Yard Remedies do a whole range of products using this blend. Alternatively PM me and I can make up a blend and send instructions on how to do it yourself going forward.
Really I suppose it's all about focusing positivity and using props (crystals/stones) to aid you to do this.
HTH!!
