Has my ‘friend’ given me nazar?

Asalamualaikum,

I have a ‘best friend’ who has been making very sneaky remarks about me for some time. Constantly saying that I’m privileged to have such and such that she ‘does not have’ and making snide remarks about me as well. She has also said many times that ‘I get whatever I want’ while knowing nothing about my life.

For the past 10 days, everything has fallen apart for me. My friendship with this friend is rocky as well right now. My studies are being negatively affected, I’ve gotten extremely sick, my appearance has dulled, I feel lazy and my body feels heavy, I’m unable to do anything and I’ve been neglecting some of my worship time as well, I don’t want go anywhere anymore including the places that made me happy, I don’t feel like eating, I constantly cry sometimes over absolutely nothing, etc.

Is this nazr? Please help me. If so, how to deal with it.
