Disappointment over birthday present reactions

Edit: Thank you so much for the lovely replies! We ended up having a lovely day and I feel a lot better. I do really think she enjoyed the presents overall, and that she had a good day. We kept it very low effort, she just had her friend over, had a meal and watched a movie. She also had her first sip of beer which she hated lol

I feel so silly... She doesn't have a very strong or enthusiastic reaction to anything, but when I see her open her presents with a blank face, I feel so incredibly crushed. I feel like I haven't succeeded in getting her things that she is happy about. Plus there's a twinge of resentment over the lack of gratitude, which I know isn't deserved.

Daughter is 18 today, and you'd think I'd be well versed in how to deal with this, I've mastered a lot, and am very bonded to her as her own unique person. So I feel very daft for feeling this way. When everyone went off afterwards, I even privately had a cry about it. I talked to my husband who's reaction was 'this is just how she is, it's nothing to do with the presents or anything... She's never shown excitement over presents'. This should make me feel better, but it didn't.

Even my youngest verbalised her disappointment over the reaction to the present she gave, and that made me really want to cry!

I don't know why I really posted this... Maybe to vent or have some reassurance? Gah. Thanks in advance.
