OVERBEARING MOTHER?

Does anyone else worry sick about their children? My son is 13. His dad and i divorced when he was four and I quickly remarried. I trust NOONE with him. I've been witg my husband for 8 years and still have an extremely hard time leaving him alone with him due to my past childhood experience..and when I do leave him I get extreme anxiety and think the worst possible things. :( so I try really hard to avoid doing so for my own peace of mind. When i do leave him i always pester him to make sure he is okay when i get back and he hates it :( and i know im probably doing more harm to him then good being overprotective. I just can't tell sometimes if what im feeling is real or not. And i know that sounds terrible :( I just wish I could. Relax and not think so much!!!
