Those people are just ignorant, don't pay any heed to them. But I can understand how being a little different due to your gift could be annoying sometimes, that's totally understandable.

Honestly, I think you could make great use of your gift you know. Yes there are ppl with demonic attachments who might not believe you and they are ignorant for their own bad, but I imagine there'll also be people with demonic attachments who will believe you and take it seriously and do something about their situation. Because many people are just totally unaware, and having this revelation about having a demonic attachment would really really help them because then they can try to fix the root cause of their problem. You could change people's lives for better.
