Intense fear of SIDS?

Does anyone else have an intense fear of SIDS? Baby girl is 3 days old and I'm freaking out. I can't even sleep when she's sleeping because I'm terrified that something will happen and I won't be able to help her. I have to find a way to overcome this before I burn out, 3-4 hours of sleep per day/night is not long term sustainable. Any advice?
