Sometimes I feel unsafe about my mom. She talks about me behind my back (usually good things like my grades, but I feel like she's treating me like some kind of trophy), she's embarrassing, and she volunteers me for things I don't want to do.
I wouldn't say it's a good thing. I feel like my mum is a friend to me more than a parent, like I feel comfortable telling her things that I would tell a friend, but I know some of my friend's parents aren't that friendly with them and are more of an authoritive, respected parent (if that makes sense). But that doesn't mean they use fear to control their children, it's just like they've not as, I guess, informal with their children. Althought if you do feel scared of your parents, its not an 'unnormal' feeling to feel, emotions are valid.
It's hard to really know what constitutes as "normal" in the first place lol. It feels like having a dysfunctional family is normal to a lot of people, including me! I mean if you do feel that way then that is not abnormal at all because you cannot control your feelings and they are completely valid, however, it is saddening to think that a lot of children do feel that way about their parents. For a long while I lacked trust in my parents, mostly because of my own faults and mental health issues, but I felt perhaps like if I told them some of the thoughts or secrets I was holding up within myself that I could get into some trouble or danger so I was trying to protect myself. But as an adult my parents are much more relaxed and so I feel like I have more trust in them now. :') But if you do ever feel that way about your family then please reach out and speak to someone, it's not a healthy environment for anyone to be in.
I think some people need to learn the difference between common and normal. Yes, this unfortunately is common and I have experienced uneasiness and a feeling of being unsafe while around my parents, particularly if they ever argue. What this is not, is "normal". Parents should not make their children feel uneasy or unsafe, they should be the ones that make you feel safe! If it's only happened once or twice then it's nothing to worry about I suppose, it isn't too much of a serious issue and if you are willing to let it go then it isn't a problem. If, however, you are constantly feeling on edge around them then you could always talk to someone about it. Phone up a child-support service, their calls are not traceable and they won't actually do anything apart from help to comfort and reassure you. It may sound stupid but it can be helpful to many people. (if you are worried about getting your parents in trouble, they won't take any sort of action unless you are in danger so your parents don't even have to know you phoned up)
All in all, it isn't normal but it is becoming more common, as long as it isn't serious you have nothing to worry about! Good luck~ <3
