It is ok to make mistakes and it can take time to develop commenting etiquette. I have definitely made mistakes in the past. Your intention was correct. Sometimes it helps to remember that we can't see faces or hear reactions in the posts. I have found using less direct language can be helpful and to think of things as suggestions, options and possibilities. Especially in such a stressful situation we could do better to come across as hand holders. Learning is a continuous process. Your heart was in the right place.
