Dealing with anxiety

So this is my first pregnancy after miscarriage, I should be about 6 weeks today. This morning I woke up and my breasts seem to have deflated, and they are barely sore. I’ve still been wearing my Ava Bracelet (obviously I need to stop) and my resting pulse rate and temperature have dropped. MS hit me like a wave this morning, but that’s about it.

I’m just wondering how everyone deals with the worrying? I did a great job staying positive up until this point, but the dread has been creeping back in. I’m already prone to anxiety, and the worrying just ends up making me worry more. Any advice? Mantras? I know that fear and faith can’t occupy the same space, but I think the fear is winning.
