Thank you for your Question.
Allah never misguides anyone. It is ones own doings that misguided him my brother.
I don’t see any fruit of the friendship.
Friendship does not mean respect for one another. Rather it means to have things in common where your thoughts are in harmony with one another and your compatible with each other in many things.
In your case, I don’t see this!
I would suggest you give your friendship a different look and look for other people to be friends with.
A friendship that ends up to be mental and physical disturbance is not a friendship.
Mind you, I’m not saying to cut ties with the person, rather while maintaining your friendly gestures, you must associate with other people who will pull you close to Allah, and make you feel like your real self again.
Take good care of yourself. It is very important
