I know the same feeling, it was worse when I was in school and away from my family during the day. I would cry and go into panic attacks almost everyday and would have to be drugged just to walk into the school door. It was very traumatic and being near a school today makes me panic. I would just sit and obsess about what my mom was doing and if it was safe, I always asked her to stay inside the house and lock all the doors until I got home and not to drive. Now that im homeschooled its not as bad because I with her everyday but when ever she has to go somewhere I always go with her because I fear for her safety.
