OP - your post about periods and sanitary protection and those of others has struck a chord with me tonight. I normally post under a different name, but as other children of Narcissistic mothers will attest, no matter how confident or successful you appear on the outside, the shame that goes hand in hand with having been raised as a child who is 'not likeable/cold' never leaves you. It is also quite taboo to admit to others that you actually don't like your mother. And frankly, why should any of us given the emotional burdens we have been left with.
I too had a mother who was emotional volatile, clearly favoured my younger sister and would not answer direct questions about periods aged 9. She told me they 'were a time in history!
I remember thinking 'why is it that Sarah's mum at school thinks she is allowed to know, but I am not?' At that point, the minimal trust I ever had in her evaporated. She only told me when my younger sister was at the age that she needed to know. And of course we were told at the same time. I never had my own ST's, could only access them if she left her own in the bathroom and tampons apparently were 'the work of the devil' and 'I would die' if I used them. I couldn't understand why friends mum's thought they were a good idea. I had a similar experience with bras, never having my own - only hand me downs from cousins that were not big enough. I never got taken to be measured. Bizarrely later on, she would go to lingerie parties and buy me and my sister aged 13/14 highly inappropriate red and black camisoles/French knickers which stood out in the changing room at school. I too, used to use birthday money/lunch money to purchase tampons which I hid carefully in my room or I would have to use tissue paper stuffed with cotton wool. I was constantly certain I stunk during my period and did not know what to do about it. When I think about it, I want to run back to my lovely 14 year old self and hug her and tell one day this will pass, and tell her she is pretty and smart, and she will get through these times and one day, having been extremely successful she will be loved both by her husband and daughter. She will have friends and will genuinely be liked by others. My mother used to reinforce how pretty my sister was to everyone, and how much better she was at everything and how likeable and kind she was. Apparently I was 'selfish' and 'only thought of myself'. school was my refuge but I didn't feel good enough to have friends. Anyone who wanted my company was 'using me'. The state of our house meant I didn't want friends to see how we lived (it was dirty and unkempt) and my mother didn't work. She stayed at home and smoked all day and watched Tv. Mothers who kept a nice house were dismissed as 'houseproud obsessives'ironically my sister has the lack of friends and I have my close friends who are like my sisters. My mother constantly tries to befriend them even still so she can gossip about me and how terrible I am.
Like a previous poster, I also suffered from a mother who didn't encourage washing, brushing of teeth or hair and I didn't have clean underwear often or clothes. It was totally middle class neglect.
My own daughter has started her periods aged 11 and is totally cool. She has a variety of products in her room and she is so very loved. Unfortunately my experience of being a scape-goat sibling means I only wanted one child to love fully. Which I do. She is smart, funny and secure and is so lovely and kind my heart could burst with pride. I have found the stately homes thread very helpful and would encourage anyone with similar issues that they are trying to process to read them. Big hugs to you OP and others on here and know that your stories are believed.
