You may want to look on youtube at videos on narcissistic personality disorder. Rages can be a symptom of that. There are coaches on-line that teach you how to protect yourself. I can recommend Dr Ramani, Anna Runkle, and Dr Daniel Fox. Look up the 'grey rock' method. Also be careful that you are not being used emotionally by your mother as a 'flying monkey', or that you are being 'parentified' (i.e. your mother is the child and you are the parent that feels you have to protect her). Not saying that this is happening, but it is something to be aware of.
