[true, the thread is several years old, but the op recently posted again.}
my advice: if you had cancer, you would probably pray, ask others to pray with you, and go see 'cancer experts' (doctors).
so, if you're having sensations of demons attacking you, pray, ask others to pray with you, and go see 'sensation experts' (psychiatrists, psychotherapists).
May the Lord Jesus bless you and keep you!
