I don't have any attachment to my mother, we never bonded and she had mental health problems that made her a terrible parent. So this does happen, although your feelings towards your mother might not always be the same as they are now.

I've maintained a relationship with my mother for reasons I won't go into, but with hindsight I wish I'd known a way to set boundaries from the time I was a young adult, and to have a conversation with her where I could stay calm and not let her push my buttons. (I wasn't in therapy, and had no idea about assertiveness skills or things like that.)

My mother is still controlling to a ridiculous degree, and that comes from her being anxious and afraid. But her behaviour never got better, and she never tried to get help/therapy, because everyone in the family let her be like that. I wish I'd known before now how to calmly refuse to be part of it. The few times I've managed it, her behaviour has got much more reasonable and I 've felt OK around her, but I haven't managed it much.

I think it must be difficult as a teenager, because your mother will have control over aspects of your life. Also - dare I say it? - naybe you might not always behave perfectly! But as you get older and more independent, I recommend choosing a straightforward, adult way of communicating with her. IMO controlling people need to be given clear boundaries because they won't put any limits on their own behaviour.
