Without getting into writing a novel...
I have no reason to scoff or not believe what you have written, but I know a few family members that suffer with similar issues in various ways. Bottom line is that past doors being opened or allowed to be opened by others can ultimately be HELL to close up again.
I have no idea of your background or what you previously may have been involved in. If you have ANY kind of physical or spiritual abuse, mystical, occultic or mind altering (spiritual vision or hallucination) drug background then those doors have to be fiercely fought for to close up. Sounds like you may have generationally been brought into the demonic fold.

It is incredible that you found the way to true life in Jesus, and He is the only real way to finding peace in the Storm. He is not just another helpful spiritual force. He is the answer to all in this earth and has ultimate authority over all in it.

But from what I have experienced in my family , a complete and utter shut down and cutting off must be decided on and the Word of God declared and persisted in for the past to be minimized and ultimately made mute. All things past must be cut out with 100% certainty and given to the Lord. Includes persons, things and PLACES. Follow in trust and faith only what is revealed to you in word of God and the Spirit of God. No matter what people tell you.

In my humble opinion and experience it needs to be thoroughly shown, over TIME, to these demonic forces that they have no hope of getting their claws back into you and your family. Fight for your family spiritually. Give no quarter.
None of this can be ultimately finished simply through will power, it must be through your utter belief in the authority given Jesus, coupled with your will...and I'm sure you know that at this point.
Let fear turn to peace in the midst of the storm through utter trust in Jesus and the promises of the Father and renounce all ties to your past. Don't let your feelings guide your mouth and actions. Let the actual Spirit of God work through you in battle. So much more, but no novel.
Being merely "saved" or born again is a starting point. Not the end all. Despite what TV preachers would have you believe. It is now time to take up arms and battle to the death.
Enduring will reap freedom, and result in powerful testimony.
Million other things can be said and advised, but as I don't even know that your issue results from this particular way so I won't go on.
