Aww don't worry too much, 18 months is actually still within the normal range for independent walking, so your girl still has time! A lot of kids at this stage are already cruising along furniture confidently but just feel anxious about that final "letting go" moment, which sounds exactly like what your daughter is going through. What I've generally heard works well is sitting a short distance away and encouraging her to walk toward you with her favourite toy or snack as motivation, keeping it fun and low-pressure really helps because too much coaxing can sometimes make them more resistant.
