stcy: this is textbook normal. I realise it may be very stressful for your mum, but the alternative probably feelis like it will kill you! It won't, you know, but that does nothing to curb the feeling that it just might. You are so scared and alone, and the one person who is supposed to be there is for now. Try venturing out to more scary places with her, and try taking a few steps away from her while there. She will feel more empowered in being able to help you wean from this dependence, as opposed to feeling the object of your dependence. Try maybe a movie, as sit a couple of seats away. That way, you can see her, but you also have your own space. Others amy have hurt you, but alone, you are strongest, thought you do not yet know it. Keep posting, and let us know.
Hang in there!!
