Estee,
Your daughter is very fortunate that you were willing to risk her rejection in public no less to try to show your love for her and reach out to her. I am sure she knows how much you love her if nothing else this was a good reminder. However this probably was not an easy interaction for her either because she most likely loves you as well but is trying her best in her own way to live up to the standards set by the JW's. It's a "mom thing" to worry about kids even from a far but perhaps she was simply having an off day so try not to worry too much that she is not doing well. (easier said than done for a mom) When family that are JW's ask you to respect there boundaries about not contacting them it is a very hard thing to do (I know this) - but by not doing it they feel you are not allowing them to live life the way they need to in order to survive in the organization. Besides it could end up causing a lot of problems for her if another JW saw her with you. However I do think the idea of leaving flowers for her at work every so often is a lovely one...this way if she ever needs/wants to reach out to you she will know you have not closed the door. Wishing for you to one day have the type of relationship with your daughter that you desire and deserve.
