#1: Holy Water
Mix that blend together, and then focus on what you feel is well and good with this world. If you were raised a Christian, then the Lord's Prayer works quite well:
Ideally, one would already have protections in place to keep something nasty from happening, but when that's not an option and the mess has hit the fan, there are a couple of tips and tricks worth keeping in your back pocket.
Our Father who art in Heaven
Hallowed be Thy name
Thy Kingdom come
Thy Will be done
On Earth as it is in Heaven
Bring us this day our daily bread
And forgive us our trespasses
As we forgive those who trespass against us
Lead us not into temptation
But deliver us from Evil
For Thine is the Kingdom
The Power
And the Glory
For ever and ever
Amen
#2: Prayer
One such prayer I heard in a song, some time ago, has stuck with me:
"Universe, wrap your arms around me.
Make me strong so I can take on everyone."
- from "Why I have my Grandma's Sad Eyes" by Kill Hannah
#3: Enchantment
Taking the Holy Water and prayer above, procure a black candle, a plate, a lighter, and some bay leaves. Light the black candle after placing it on the plate and proceed to burn the bay leaves while reciting the above prayer. Recite it until you feel it, then you can either let the candle burn out or snuff it out. The choice is yours, but after you've done this, you should feel better.
If not, and you're still feeling as though you're up a creek without a paddle, I recommend seeking out assistance. Those tools are pretty potent, so if they're not working for you you're either doing something wrong or what you're dealing with is out of your league (and thus you need help).
Take care folks,
