But I’m very thankful that no one is slamming my head against the wall anymore.

Taken at face value, the line uses vivid physical imagery—having one’s head “slammed…against the wall”—as a metaphor for sustained pressure, conflict, or emotional battering. The pivot to gratitude (“very thankful”) suggests a transition out of a damaging environment: a relationship, workplace, addiction cycle, or public scrutiny. The wording implies relief more than triumph; the speaker is not claiming everything is perfect, only that an acute, repetitive harm has stopped. As a quotation, it functions as a compact testimony of survival and boundary-setting, emphasizing the value of simply ending ongoing injury.
