Anxiety about losing child

Does anybody else go through this and have these “fears/thoughts”? I get these intrusive thoughts of my children. I think it’s because that’s my biggest fear in the world is to lose them. But why do I have it more with my first child who’s 3 than my baby who’s under 1? Like everyday im more worried and all these scenarios come to my mind and it terrifies me. Like in the car I’m scared we will wreck. When we’re playing outside or at the store I fear someone will kidnap her. Those are just two examples how do I overcome this fear? Why is it towards her more than my other daughter? It don’t mean it’s a “sign” right? 🤦‍♀️

( I’ll make an appointment with my therapist)

But can anybody give me some insight I hate feeling this way. Any tips to make it stop and is this at all normal? 😞
