Don’t worry Sally I’m trying to do the same and I’m 26 ha. I think you just have to plan out how and what you want to tell them.. my PC suggested telling your more supportive parent first then it may be easier to tell the second. For me, mines all about lack of self confidence – I always have to buy x3 boost push up bras, I’ve never been on holiday cause the thought of wearing a bikini is too much to handle, the fact I feel out of portion (I have wide hips and a big bum) and I know my body isn’t going to ‘change’ anymore . Giving a reason on why you want it done is probably going to be accepted more.
