I was hoping so many things were 'a thing of the past', but alas!
Based on some of your posts, notably last season, you have been displeased by the expression on Alina's face before and after she skates when she doesn't reflect a confident, secure, radiantly happy skater enjoying herself. It makes me sad to see her sad too. I don't like seeing her be hard on herself or disappointed with herself, but she is a 17 year old girl before she is anything else and I would rather her be true to herself than not.
Let her be who she is and feel what she feels. Even if that doesn't always live up to the expectations of how a happy skater is 'supposed' to look. Is there any highly competitive athlete who is less than devastated when they feel like they haven't performed at the level they believe they are capable of? Some are more stoic than others but it's not a character flaw to show your feelings on your face. It just means Alina probably shouldn't play poker!
Some athletes get nervous before a competition and it shows on their face. It is what it is. Her beautifully expressive face is one of her best assets and her ability to be in touch with emotions, positive and negative, is something that will help her grow as an artist. If you take that away, you take away an essential part of who she is. I would also like to see her in the K&C laughing off her mistakes and taking it all lightly, but that's not her. If one thing is different, everything is different.
Not everyone has to like her, her skating, her ability, her artistry, her personality or even the expression on her face. No skater has ever universally appealed to everyone and no skater ever will.
Alina will find her own way through her life. No victory or defeat is ever final and it's a long road. Injuries happen and they heal with time. The only thing certain is change. Especially at 17.
To 100% clear - it broke my heart into a million pieces to see her that devastated. I don't think anyone on this forum thinks its 'okay' for her to be unhappy. (If they do, please don't tell me about it.) But it is an unavoidable part of any life with or without competitive sports. It is not the first or the last time she will be hurt in life. If this is the worst pain she ever feels then she is one of the most blessed of all human beings.
Wanna see radiating Alina?
