Anxiety

My baby is 6 weeks old and it seems like at night I really worry and dread the nighttime. The waking up during the night (thankfully he only wakes up once but I feed then pump so I’m usually up over an hour). And every night I just worry about things, like SIDS, and just thoughts that bad stuff is going to happen. I hate having these thoughts. But SIDS scares me so much and I can’t help but to worry. I really only worry at night because that’s when I can’t watch him or check on him like I do during the day. Does anyone else feel this way?
