Muslim girls did black magic on me

Long story short, I went on a girls trip out of state with a group of my sisters friends. I myself am Muslim and the group of girls are as well. Myself and another girl forgot to bring our hairbrush so we went to a nearby store. As I was about to purchase my own hairbrush the girl let’s call her Sara mentioned to not get one that we could just share since it was only a few days. I thought it was strange but she was adamant about this. Once we got back to the hotel, Sara mentioned how she didn’t need the hairbrush because she found hers and that I can have it. (She payed for it). I thanked her and continued to use the hair brush. Unfortunately there was a lot of drama on this trip, bullying and mean girl behavior. I being an outsider from the group was ostracized for calling out said behavior. I stood up for myself and was hated by the entire group for speaking against their leader of the pack. I never in my life met such hateful, racist, ignorant and horrible people. I was astonished my sister kept this company around her and still does. That’s why her wanting to share a hair brush then letting me keep it I found was strangely kind but I took it as a genuine gesture.. By the end of the trip I was emotionally exhausted and even mentally suffering by their sheer bullying. Anyways back to the central theme.
The night before we are scheduled to leave, everyone is packing. Sara asks for the hairbrush back, which I thought was strange since she said I could have it earlier. She paid for it, so of course I returned it. Before returning it to Sara, I said “there is a lot of hair in the hairbrush let me take it out real quick” she said “NO, no no that’s fine I can do it later”. I had a weird feeling but ofcourse I was not thinking that far ahead. So stupidly I gave her the hairbrush back with my hair in it. She quickly put the hair brush away packed into her stuff. She did not need to hurry or rush but she was awkwardly fast putting it away.
I thought it was super strange as there was a lot of hair in there as I shed alot of hair and she didn’t even bother removing it. I try not to judge people’s intentions as that’s what we are taught as Muslims however I have many reasons to believe they used my hair to do black magic.
I overheard them talking in between the lines horrible things about me and how they wanted the worst for me. At this point it was too late to retrieve the hairbrush as we were leaving the next day. I did not want to confront them as it was a very toxic environment and I was singled out. Shortly after the trip, I fell very sick out of nowhere & everything started unraveling for me, horrible things randomly started happening. I told this situation to a friend and she agreed that these group of girls were not only capable of such things but have done worse to others.

This was about 6 years ago and Sara has been to Umrah multiple times and I can’t help but think how do people like that get invited to go. These group of girls including Sara tried to ruin my life and in some ways succeeded. I can’t fit everything they did here it’s not just the black magic but many other things. I had to get counseling upon my return and I have never had to do anything like that before. I know it may sound trivial in this post but immense bullying over a period of a week, being singled out and having your sibling not protect you is devastatingly damaging for a very young adult.
I don’t let it hurt my own faith to think this way but sometimes I question why does Allah bless this person, Invite them to umrah and keep them healthy but good genuine people struggle.

How can I move on from this and feel safe? I pray a lot and ask for protection but black magic still affects people so I’m worried that the harm they caused me will never go away.

Sorry for all the typos I typed this fast and late at night.
