Strange treatment!

10 years ago I saw how some old person beat my cousin (he had 14 years) so I was too scared. I can’t sleep at nights and I can’t be alone. My mom was desesperate and she ask to my grandmother how can she do, my grandma told her than she know an elderly person who could remove the fear. The next day we went to the elderly person house then I lie down on the bed and she star to pray and passing over my body herbs and something like smoke. I don’t know what she did but after that I start to sleep again.
