Im not someone who believes that other people can actually curse us .. nor do I believe in possession ... that said those are very scary and powerful fears and really need to be looked into.

maybe a chat with the religious leader of your faith would help?

I suspect that life events may have caused you great anxiety and deep seated stress and that because you have religious beliefs they have attached themselves to your belief system.

You are sane, the fact you are questioning this says that..

maybe list all the good things in your life to strengthen yourself.. remember too that this lady you talk of is just another person.flawed andable to make mistakes..there are reasons why she behaves as she does but I think they are psychological rather than spirit induced.

Now im not sure what I really think about "God" but Im sure that a good and loving god would give prayers to harm others any satisfaction..

Sometimes it looks as if their prayers are answered in the ways they want but again Id gently suggest that when we expect bad things to happen they then interpret things that happen as being answers when they are just things t5hat happen because of the way the worldjust is.

These thoughts , ( in my post), are more me ruminating on things than basedon any real evidence..all id ask is that you think about them.
