I think so many mothers go through this - but I would absolutely echo what the others have said - if she feels you're on her side then you're not doing so badly.
I don't have a perfect relationship with my mum, but we are good friends. She has been, in many ways, a very strong feminist influence on me. This is what she taught me about life, from a young age: that I am a worthwhile person, that I can be strong (even if I don't feel it), that I can do anything I set my mind to, that men are not the be-all-and-end-all of life, that no man has the right to control me or make me feel bad.
I also had a very strange time in my teens where I withdrew completely into myself, and into a world of books and music. Had few friends, went out rarely. I'm forever grateful to her that she didn't make a big thing about this, and just let it run it's course - which it did, when I got a weekend job and met some new people, and then when I went onto university. I think this is a very,very common phase in teens.
Have you got anyone at all in real life that you can start to confide in? I suffer terribly from anxiety sometimes, and I would be totally lost without girlfriends to chat to/share problems with. A close female confidant is one of the things that can make all the difference to your mental well-being. I do understand how an abusive relationship can ruin your confidence and trust in others though
Who do you think you're closest to irl?
