I, obviously, appreciate getting gifts, but I \*dread\* having to open them up in front of people. I hate how I say "thank you :)" when I receive gifts because it always sounds the same. I always smile when I talk, so it's already hard to tell. I'm bad at getting the right tone for it, so I'm always afraid they think I don't like it, even if I really do, solely because I don't sound \*that\* excited when I say thank you. Like, what if I hurt their feelings because of that?? I don't like the attention on me either because then everyone is literally watching you...and I can't get out of it because last time I did, my parents were disappointed in me and then I felt even worse. 

Any tips are appreciated on how to deal with it, I really don't want to have to keep freaking out over this and get very little sleep until the holiday my family and I celebrate arrives..
