Many years ago, a co worker found out that her husband was cheating on her with one of his co workers and left her, 3 days before Thanksgiving. She was devastated. Everyone around her invited her to their house for Thanksgiving, all with the best of intentions, including me. When someone said to her "You don't want to be alone on Thanksgiving", she replied " No, YOU don't want me to be alone. I don't know what I want." She was right.
Your family and friends are just doing what they think they can to help the situation, even if that isn't helping much at all. Take a deep breath and just keep saying "One more week" until it's all behind you.
The anniversery, I just had my 20th, alone, the day before surgery. Fabulous pity party I threw myself. Wish everyone could have been there, but more lucky for them that they were not. It [censored], no two ways about it. This too will pass, and we will come out of it stronger. Promise.
