Separation anxiety

Everytime I think about leaving the house without my baby I get bad anxiety. Even when I leave the room for a moment I'm in a rush to get back to the room.a couple times I've cried when people offered to help .  How can I get over this ? Did anyone else have this problem? I do have people Around for help and support but I'm so scared he's going to choke and no one hear him . Please help I don't want to be a over barring mom. And I know it will probably drive me into a depression
