I'm curious about the meaning of the expression '발목을 붙잡다' in Korea.

I need an understanding of the Korean expression '발목을 붙잡다'. This expression is used like in the sentence '트라우마가 저의 발목을 붙잡더라도 계속 이겨내야겠어요', and ChatGPT translated it as 'Even if my trauma holds me back, I'll keep overcoming it.' '발목을 붙잡다' does not literally mean to grab someone's ankle, but rather means to hinder someone or block progress. So, when this expression is used, does it really signify a serious trauma, or is it just a general expression indicating that something is being obstructed? Is this expression commonly used in Korea, or is it only used in specific situations? Is there anyone who can help me understand this expression?
