Violent intrusive thoughts

I am attending therapy for this and i know I wouldn’t act on these but they feel so real at the time.... i hate my boyfriends mother and siblings... it’s almost an exaggerated deep hatred and i often have intrusive thoughts about severely hurting them.... stuff like beating them up or saying such horrible things to them :(. I told my boyfriend about this and he is empathetic and understanding and knows i would never do it, he knows they are thoughts and nothing else.... it really gets to me at times. Have any of you had experiences with violent intrusive thoughts?
