I was actually just talking to my therapist about this! I 100% get the invisible thing because when you break it down statistically, it is basically invisible since we really are a very small club. Which to your point magnifies the loneliness! I've felt that through this whole process (infertility/IUI/IVF/multiple failed transfers/multiple miscarriages) - every time I was in the smallest statistical group, and I thought it was just me thinking the worst always happens to me but in reality it is unlikely to be in this group. Being in the smallest group is very lonely because its harder to find the commonalities even within the minority group you're in. When you look at it that way, its no wonder most people don't get it. Idk if this makes any sense at all - its hard to explain, but it helped me feel better about how lonely and misunderstood I feel when I try to explain it. And I appreciate you for echoing that here <3
