Oh Meme, I am so sorry you are feeling so bad and so scared. When did this all start? Who exactly said they will get you? You will NOT go to hell, ever and they won't get you but I know its easy for us to say. You are very safe on this forum, we all love and care for you.
Was does your support worker say about this fear?
You are an amazing woman to live through this and care for your little boy.
Being tired from lack of sleep will amplify your feelings of fear too.
Please let us know how you are today
