High anxiety during TWW

A

I have anxiety and it tends to take over after ovulation. We started trying again so I make it a few days into the TWW and anxiety, beyond my control, kicks into high gear. My biggest symptom is tachycardia. I don’t want my body to think controlling the stress is more important than conceiving. But I hear it’ll do that and interfere with having a baby. Anyone that relates, how do you control this??? 😢
