I think I've been misunderstood here. The baffling part was related to ME. It's me who can't understand how other people can be so confident because I'm an autistic person who already struggles to understand NT brains anyway. And, as a person who thinks negatively, I can't imagine being positive about something that frightens me so much. Hope scares me. Hope gives me more to lose.
BUT
I never said that there's something wrong with people who prefer to think that way nor did I call anyone stupid or idiotic. I think it's admirable that you're all able to be positive in the face of all of the unknowns that pregnancy throws at us. I'm sure all of you are right and justified to think that way and I've never said that anyone won't end up with a baby bar myself.
I wish I could be like the rest of you, but I'm just not. Please be as optimistic as you want here or anywhere else. I was only ever negative towards myself and I have every right to think that way about my own personal circumstances.
