Literal
She [topic-は] own-self [subject-が] torn-apart [like-ような] feeling did.
引き裂かれるような気がした (felt like being torn apart) layers passive 引き裂かれる (to be torn apart) with ~ような (like) and 気がする (to feel). The compound verb 引き裂く (rip apart) in its passive form creates a visceral metaphor for emotional distress — she felt herself being pulled in different directions or experiencing internal conflict so intense it felt physical.
