First I just wanted to say that it's okay to feel what you feel. The last thing you need right now is an additional burden of guilt for losing your faith. I think that we all go through this sometimes and hopefully when you go through this rough patch things will get better and your faith stronger. I hope things get better for you soon. If you ever need to talk, please please contact me, i would like to help if I can.
A Dark Night of the Soul is no easy thing to go through. Take your time with it. I've had a handful of those myself, and they're never easy. The important part is to take your time and don't force anything. The more you force yourself to go one way, the more uncomfortable you will be. My advice is take it as a lesson or series of lessons.
Also, you are never a disruption here. Your prayers are as valid as anyone else's. You are going through a hard time. Trust that God is all around you, even if you can't feel it. He is guiding you on a journey. Where it goes, no one knows for certain. We're here for whatever you need.
Here is a prayer/spell that invokes multiple spirits to cleanse an object or location of negative energy: In the name of Jesus Christ of Nazareth, I apply the blood of the lamb over [name of location/items] . I beseech St. Michael and the Powers to combat all demonic and negative-energy based spirits within [name of location/items] . I beseech Kali, the dark goddess, to trample the pride of the servants of evil. I beseech Sanat Kumara to shatter the strongholds that the demons have over [name of location/items] . I beseech Maat to cleanse [name of location/items] of negative energy. I beseech Cassiel, Camael, Phanuel, and Ishtar to smite the forces of evil within [name of location/items] .
Note: Make sure you are honest when invoking Maat, otherwise you might face trials in life, meant to help build up your integrity.
Jehovah Sabaoth, thank you that the battle is yours. Let conflict fold in your mighty presence. Make troubles melt in your glory. Cause giants to fall at the power of your name. Be magnified and show your strength on our behalf! Grant me strategic wisdom to know how to position myself as you manifest the victory.
O Holy Angels, watch over us at all times during this perilous life: O Holy Archangels, be our guides on the way to heaven; O Heavenly Choir of the Principalities, govern us in soul and body; O mighty Powers, preserve us against the wiles of the demons; O Celestial Virtues, give us strength and courage in the battle of life; O powerful Dominations, obtain for us dominion over the rebellion of our flesh; O Sacred Thrones, grant us peace with God and man; O brilliant Cherubim, illuminate our minds with heavenly knowledge; O burning Seraphim, enkindle i our hearts the fire of charity.
