I don’t think it is occultism. We all endeavour to fight our battles with our own will power , it’s part of our human way of doing things. Occultist would be relying on something evil that is separate to you.
Relying on another spiritual force that is not of God …..that doesn’t sound in line with what you have shared.
Often as not when we don’t gain victory we presume that God is not working or helping, so we tend to get impatient and try and sort it out ourselves. It’s about working with God , in many respects it’s about realising that by ourselves we cannot sort things out ,that’s the point.
You have already admitted that you have done this and already realised it’s not that simple to achieve. The Lord knows YOU , your battles, your weaknesses , your desire to sort this…….your life is valuable to HIM.
I don’t know the answers, but know for a fact that God does xxxxx
Will be praying for you. Xxxx
