I hear you, I hate hearing negative things about myself too, but the thing is in an environment where there is never ever any criticism, how will anyone ever improve? There would really be no point in the performance management/probation/appraisal processes if all they were was universal praise and thanks (there should always be an element of these of course!)! I get that you always put 100% effort in, but sometimes with the best will in the world, for every single one of us, effort is not enough, no-one is 100% perfect at their job all the time. Sometimes you do need a third party to point out things you could change or do differently which probably would never have occurred to you by yourself. Of course, at other times feedback is a load of bollocks of course, but as per above, no-one is perfect, so occasional mistakes/misconceptions happen and just have to be written off as such!
Receiving constructive advice and guidance is absolutely not a sign you are failing or bad at your job, in fact personally the only people in my team I have never and would never give any feedback to are the ones that actually are so bad at their jobs and/or have such negative personalities they are effectively a lost cause, they would never be open to trying to improve or better themselves in any way. So in a funny way I would try and take it as a compliment that your boss thinks you are worth taking the trouble to give personalised feedback to, even if her way of telling you this wasn't the best (as PP says it's a real skill giving people feedback nicely but honestly, not everyone has it!). I am assuming there were some nice, positive things mentioned too, as well as the points to improve on, but like most of us I expect you have zero'd in on the negative?
In terms of how to take it, I think the vast majority of people don't really 'enjoy' hearing negative feedback and find it at least initially unpleasant and annoying, IMO most people have one of two immediate, emotional, kneejerk responses to negative feedback (sometimes both!): either they feel sad, anxious, even tearful, they worry that this means disaster/they are terrible at their job/their boss hates them, OR they get defensive, angry, deny it's true, feel this means the world is against them or or the person giving the feedback is stupid/plain wrong. Both of these are quite natural, normal cognitive responses - feeling these things doesn't make you a bad person or emotionally messed up - in fact 'normal' brains are hard wired to stick to our current belief systems (ie that we are great at our jobs and never make mistakes
) and to be fearful of anything that could be a threat such as a boss or influential person criticising you. Sometimes it's described as the primitive/'monkey' side of our brains taking over.
It's a bit cringe-y, but I personally feel the best way to overcome this is when someone is giving you feedback, to just concentrate on 'receiving'/ 'hearing' what is said to you, understanding and memorising what is actually being said (very easy if you get overtaken by an emotional reaction or by an internal voiceover track arguing with what the person is saying, to focus in on one small part, and forget most of the rest of the conversation!), and try and 'park' your reaction to it, whether you agree, what you are going to do about it etc., for a later point when you can examine it calmly and in private. View it as like an unwanted gift at a birthday party from a well-meaning elderly aunt - smile and nod, thank the 'aunt' / feedback giver (through gritted teeth if need be) and avoid engaging in heated debate or argue/sob all over them -usually unacceptable/unhelpful professionally
. Then give yourself some distance from the conversation - if you need to let the emotion out and punch a wall or curl up in a ball sobbing in private or whatever do so - but crucially when you are done, then examine your mental 'notes' of what was actually said and evaluate the situation using your rational brain - is what was said true/valid? If not then just let it go and forget about it, that is a perfectly acceptable reaction (or if really, truly necessary, make a calm plan to correct their misconception). Can you take something useful from the feedback, even if you don't agree overall? Can you take some action to improve? Do you want to go back to the feedback giver and ask for more information, or help? I think really trying to approach it impartially, almost as if I was helping a friend or colleague who had received the same feedback helps (even if sometimes my 'advice' to myself is just sod it and ignore the bastard!).
