glad you are feeling a little better, and it's great that your boyfriend is being so supportive. i've read stories of a few people in your situation, and sometimes their partners have seemed less than supportive. i know for a fact that my husband is undyingly positive about everything. he would be totally supportive of me, but his understanding only stretches so far - because he would believe fundamentally that everything was going to be fine. sometimes, you just need someone who can share, empathise with and completely 'get' your fears and worries. and who doesn't try to focus unstintingly on the positive ALL the time.
i can totally understand why you are worried about jinxing it - but, like i tried to say yesterday, you can't do anything to chance the result. the baby either has the illness, or it hasn't. and (god forbid), if it has, it's had it right from the start, before you ever knew that you and your boyfriend carried the gene, and before you knew that you could be tested, and before you had the amnio. you CANNOT jinx it. so please don't torture yourself over your feelings. it's natural to sway from being positive, to being negative, but please please don't worry about what effect that will have on the baby. obviously, if you can, it's definitely best not to get very hysterical, as too much of that is not good for the baby (although some of it, i'm told, is fine - and i guess most women get hysterical on at least a few occasions during their pregnancies).
still thinking of you...
