Any field which would make you feel secure and which would help with mental distress (you mentioned Devic Intercession), also add self love fields and brain regeneration and amygdala field.
There is also a field…
I’ll link it immediately.
Paranoia might come from a lack of trust, especially in others; however, we are all connected, and if there is Goodness Within (You/Yourself), then It Is Present Within Others too.
Also, maybe it’s due to trauma or other causes.
If other fields come to my mind, I’ll link them or mention them.
All The Best, My Friend.
Also, as @Rosechalice said, you have to identify the cause, first of all.
Edit: also, watch out for anything (microorganisms, infections, etc.) which has the potential to affect the brain/mind (directly or indirectly, for example by altering the mood, to give an example), like viruses, Parasites, Fungus, etc.
