I had an expernce and I nearly died but the weak demon I had a fight with recently I may be psychic and I can't get to get whitesage I live in remote place so can anybody help me please

Can you elaborate more specifically about the whole situation please? If English is your primary language, please use proper punctuation and grammar. Why do you think you need white sage and more importantly why do you think you "fought" a weak demon?

And we don't normally fight demons

You need to rebuke any thing that is not of god and get a bible and speak the word, it's the weapon against this
