This. Every single word.
My mum suffered horrific trauma as a child. She did her best to break the cycle, and did a lot of good things for my siblings and I, which I am grateful for. However, I did not have a 'normal' upbringing like my friends, and I now have a very strained relationship with my mum. yeah, I still see her, but it's not that often - we are not close, never have been, and sadly will probably never be.
Growing up, I had to be her emotional support; as a teenager, I put her needs before my own, and it had serious effects on my MH (and that of my siblings).
OP - your daughter knows what your 'friends' are doing in your room. trust me, she knows - she just doesn't;t tell you she knows. The amount of times, I silently sobbed in my bed, due to the things I was hearing from my mum's room, and yes - I pretended that I didn't see the numerous bruises the next day. The amount of times my big sister held me and comforted me (we shared a room) because I didn't feel safe walking down the corridor, and knocking on my mum's door.
The thing that broke my heart the most reading this thread? Where you said that your daughter spent the night in your bed on Friday. I remember doing this with my mum lots of times, when she was alone. Not because I wanted to, but because I knew she needed me to. Every time I did it she would comment about how lovely it was to snuggle together, and spent time together. I spent those nights worrying and anxious.
Unfortunately, my mum's trauma became my trauma - despite me never physically living through what she had gone through. As a teenager, I resented her for never being there emotionally for me. As an adult, I understand she wasn't able to give me that emotional headspace. For years, I never got close to men - I saw how men treated my mum, and so wanted to avoid them. I'm lucky to now have a very decent DH, whom I 100% trust to never treat me like that (and yes - we didn't have sex straight away, we wore condoms until we both went for STI checks, and I firmly trust he would never ever cheat).
Ask my mum - she will tell you how proud she is of her DC and how 'well-adjusted' we are (we're not - we've all had MH issues during our adult lives), and how this is a testament of what a great mum she is, and how good a job she did in bringing us up.
So, please take note of every single word @fitzwilliamdarcy has written in all her posts. Yes, you may be making amazing changes to improving your life, but everything you do is still affecting your DDs, especially your 10yo, who will be becoming more and more aware of everything you are doing.
