Aunt Li Xia, your story is really touching, you have given so much for your family, and now you finally have the opportunity to live for yourself, you deserve it. Your trip sounds like a wonderful thing, and the snow and food in Harbin are sure to make you unforgettable. The ingredients and instructions you prepared for your daughter-in-law are really thoughtful and careful, and I believe your family will be able to feel this kind of care and care.
As for the guilt you mentioned, you don't have to blame yourself too much. You've done a great job, everyone has their own space and needs, and you need time to relax and enjoy life too. Your family will be happy for you if they know you're so happy.
Now you come home and see that there is no one at home, and you must be very anxious. But maybe they're just out temporarily, or something is delayed. You call your son and you might know what's going on, maybe they're preparing a surprise for your return. In any case, we hope you can reunite with your family soon, share your travel stories, and enjoy the warmth of family. Your life has gotten better and better, and there must be more beautiful things waiting for you in the future.
