SIDS anxiety

How do you cope with the anxiety and stress and worrying about SIDS? I seriously haven’t been able to stop crying multiple times a day worrying myself sick about it. I bought an owlet sock only to realize you have to have Wi-Fi to use it. I couldn’t figure out how to get it to work without Wi-Fi so I had to return it and now I’m desperately in search of some sort of oxygen, heart rate, breathing monitor for him at night. 😭 he was on cpap for a few hours after birth and it’s just made me like so worried this time around about SIDS and I just don’t know what to do.
