OP, I'm sorry you are feeling so bad. I completely understand. I'm in the same situation--33, TTC #2, and my temps just dropped on 12 dpo. Not sure about words of wisdom, but I'm reassured that my body can do this given I've been here before. A daily meditation practice helps me put things in perspective (though sometimes I feel like I'm going to scream). Know that you're not alone, and that overall, life is good (even on those days when AF is visiting). I'm sending really good vibes your way!
