I suffer from bad anxiety also. It sounds like you had a really tough childhood which I can relate to. It sounds like you are scared of things that may not really be happening bur apparently things have happened to you that caused anxiety. I think that it is a natural response to be filled with fear after what you have through. Of course I am nit a doctor but it sounds like your body is just reacting to everything that has happened. Give yourself permission to have the feelings and not be scared if them. They won't kill you. Just allow yourself to feel them but of course I think you should probably go see a psychologist. It's unbelievable that you have been through soo much at such a young age. But have faith you will get through it. You are recognizing it and talking about it. That is huge. Hive yourself a hug and good luck. Lol
