I agree that you need to tell her again. Just keep talking about it. It sounds like this is really important (I guess anything that triggers is important). So keep working on it. Maybe through this you'll find out why the verbal reassurance is so important for you to hear, and then it will be easier to deal with when you don't get it, especially in RL. I know you already told her, but sometimes we need to really drive the point home with them so they KNOW how important something is to us!!
