First, welcome back!
The practice of witchcraft or Wicca is such an integral daily part of my life that I don't even think about it...and it can, and will, be this way with you again.
Starting over-- as you regain the connection you thought you lost with the Goddess and this nature religion, begin with small everyday practices.
If your beliefs never faltered, it's all still there!
Do you read tarot...draw a card a day for insight and meditation?
What about baking-- make some magical muffins or cake and use some herbs to benefit you and your family in magickal ways.
Cleaning-- When you scrub the bathroom sinks, or the kitchen floor...add some herbs to magickally cleanse this space while you are mundanely cleaning it.
Do you have any altar spots inside your house?...If not create one, if you already have one, redo it. Choose a deity, theme, etc. that you feel would benefit you right now.
Make some talismans, mojo bags, etc...I just did that for my daughter's new car when I worked my "mojo" on it for safety and protection. There is now a little black mojo bag hanging from her rear-view mirror and a large stone talisman painted with protective sigils beneath her seat.
Do you protect your vehicles magickally?
Take a cleansing bath-- light the candles/incense/put on some new age music...toss a pinch of sea salt and a spring of rosemary in your bathwater...cleanse yourself spiritually while you cleanse yourself physically.
I invite you to visit The Goddess Grove. This is an online circle for women only that I created at Myspace...
