Have you seen a doctor? Pain this extreme due to a period isn’t normal and may be a sign of a medical condition.
There’s no such thing as “spiritual DNA” - DNA is a mechanism for biological reproduction, Belial was never a living entity and never had physical DNA either, as far as we know, so this seems unlikely. They probably mean something different and your interpretation of the intuition is confusing things. Mostly they’re just lying trying to get you to stay complaint by claiming a kinship.
Everything you says tell me this is a parasite - it’s all red flags for this kind of entity and your post is the exact same and many others with this issue of having possessive parasites tell them rubbish as an excuse to keep abusing them… while they lie and never actually deliver on promises - this is exactly what all parasites do. This is a big one but you can still just kill it.
Clearly not, as your post was written by you and you ARE your higher self. Stop listening to the bullshit of a parasitic impostor. It’s embedded into your emotional system which makes it hard to stick to decision around it but you can chip away at it, gain ground and it will take time but you can get rid of it.
It doesn’t. You’re it’s meal ticket and it will say anything to get you to comply. Why did you assume this was remotely the truth? From here it will make threats, attack you, hurt you and make you feel like shit, it’s looking like it’s pretty strongly attached. But you are sovereign, it’s on borrowed time and you have the high ground, time ti take the gloves off, stop trying to negotiate and get rid of it.
Do not call entities for this - your connections are compromised and you probably have more than one. I strongly recommend a long period, months even, of banishing, cleansing and going to war with these things until you are clean. Then you can try again when you have put up proper protections against such things.
It’s a common problem, see more stories around the forum or look at some common ways to get rid of them here:
Robert Bruce’s Psychic Defense handbook is also good as is the Exorcists handbook by Josepgine Mccarthy.
