Anxiety and worry about the holidays

With thanksgiving this week and Christmas coming up, I have begun to feel so anxious. We are visiting family, and everyone will be celebrating the birth of my SIL’s twins. She got pregnant the first month off bc. My husband and I have been silently carrying the burden of TTC for 2 years, and we just got news after his MRI that he will never be able to conceive children naturally. We are both 30 years old. We may be able to have kids with iui or ivf, but we are not doing very well financially right now. He hasn’t found a way to tell anyone in his family, and I understand that will be a hard conversation one day. I’m so nervous about everyone asking when we want to have children. I’m also nervous about accidentally making a snide remark. I can get a bit mouthy if my buttons get pushed. I guess it’s just hard putting up a front for so long. Anyone else kinda dreading the holidays? Any advice?
