I am sorry your post has been misunderstood.
You posted " I was asking for advice on if I had good reason to feel betrayed and hurt by my mother because I needed her help,and she turned her back on me,but told my son if my brother needed help with his medicine she would help him.....and the second was if anyone had any advice as how to deal and cope with the stress my girlfriend is putting me through.where does fear and anxiety come to play into that?"
My simple answer to your question is "stress and anxiety go hand in hand."
As far as how you feel about your mother and your girlfriend, only you can decided if you feel betrayed and if you feel it is justified.
You posted at the end of your last post "but again my questions were over my mother and girlfriend. because that is what is bothering me."
