Anxiety?

I'm a single mom and know that someday I want to meet someone else. The only thing stopping me is I'm so scared of bringing a guy around my daughter. I keep thinking I could meet someone I think is amazing and then years later he could end up being abusive(physically, sexually ect) to my daughter. It really puts me off meeting any men. I also sometimes think that what if shes in school and a random person comes to pick her up and the teachers let her go with them (they 100% wouldnt, they have a list of who can collect each child and they need to be informed if it's going to be someone other than me). Theres other stupid scenarios that run through my head and I know they are so highly unlikely. I dont know why I get these horrible horrible thoughts when it comes to my daughter, I just fear the absolute worst. Is this anxiety or normal mom worries?
