I'm sorry. It sucks when you never hear anything nice from your parent.

My mom used to greet me with, "Oh my God, your clothes/hair/makeup/shoes/" when I'd come home from high school/college/living 1200 miles away. When I was about 26 and visiting for the first time in about a year I finally said, "Gee, Mom, the way you'd talk to me, it's like you don't love me and want me around" and walked away. I didn't pick a fight but I let her stew on it. She's been a lot nicer the past ten years or so. But that's exactly how I felt - like she just had NOTHING nice to say to me.

I think sometimes parents don't "hear" how they talk to their kids. You might need to tell her that it would be nice to hear something nice for a change.
