Also, your explanation of how your parents never really say "I love you" suggests why it may feel particularly meaningful/a big deal with your T saying it. I grew up hearing it (mainly from my mom), so I suppose it feels more normal to me. It could be a good topic to bring up with your T--not necessarily going into her statement to you, but how you express it to others, how you feel when you do/don't hear it back, etc.
