No probs, Soutra
I think along with changing our behaviour, it's god to remember we can change our reactions (which is part of behaviour, I suppose).
So for langfordlady, it sounds like you're a perfectionist - you are so scared of being less than wonderful, of people criticising you, you end up feeling 'pathetic' in case you do the wrong thing and put your foot in it...and that's so limiting and awkward in relationships.
You're also looking for affirmation from others that you are doing well, and when you don't get it, you are resentful and feel as if others are getting the praise you want for yourself. It sounds exhausting But it's prob not because you are big-headed or a jealous person - but because you are low in confidence yourself, and need others to boost you.
Changing your reaction would mean re-framing your thoughts, to forget about the praise you see others appear to be getting, and to stop comparing. Are you really not being thanked or appreciated in any way at all? If that's the case, then perhaps you can ask directly the best way to offer help, and say with a laugh you are worried about getting things wrong. You'll need not to sound miffed or jealous, just genuinely willing!
Hope this comes across ok - I have a background in counselling and these are the sort of 'tactics' that can help in behaviour (rather than character!) change.
