can someone could help me with this?

So i met with a psychic awhile back. She told me i had a negative force that had wished that nothing good would come to me. Even though i have overcome many obstacles in my life i often wondered why certain upsetting things happened to me. I watched a video on youtube that said if you ask arch angel Michel for protection and wear and or keep a rose quartz chrystal or ogonite near you that should help. So lately i have worn a rose quartz chyrstal around my neck because i haven't found where i could buy an orgonite pendant. I ask arch angel Michel 3 times a day for his protection. I was wondering if i am ridding my self of this negative entity or if it will still be there.

Also, haha, I have a lot of questions, but i've started to realize i have some psychic abilities, how do i go about developing these. I believe that i am an indigo child but at times i feel so lost with what is going on in my life and i wonder if that is the negative entity playing a part. The psychic said that this entity could be whats holding me back right now from moving forward. She said i had a guardian angel but didn't help me much with explaining that to me. I hope someone can help me with what I am dealing with. Cause it upsets me that I've had something wishing harm on me when I've always wanted to help others. :(
