I don't know what you mean by "holding on". We feel what we feel when we feel it. Feelings are never "wrong" or incorrect because they are about us and to help orient us. Did you ever watch the Mary Tyler Moore show episode where they were laughing at a funeral?

If you did well in yesterday's session and knew it but are uncertain now, you are uncertain now. Yesterday's good feelings are not about now! Yes, we can think of them and use them for hope of more good feelings in the future or as examples of what made us feel good in the past (and might now) but the current uncertainty is probably not about not feeling good now "because" we felt good yesterday. There is no continuance of good feelings, they change like weather and thoughts, adjusting to current circumstances.

If I say "don't think about pink elephants" and you instantly think about them but don't remember what I said tomorrow, when you see a picture of a pink elephant; there's nothing wrong with that!

Yes, being disappointed when you don't see your post on the first page might have something to do with lack of self validation but it also is a very normal feeling! We like, look for, seek validation from others. That's what keeps us interacting with others instead of just contemplating our belly button! We are not in this world for other people; do you think you should just validate others and only self-validate yourself? Think of it positively; you are aware of what you enjoy and like; many people are not.

Why do you think singers, actors/actresses, etc. do what they do? They are no one without an audience. Why do you think you and I post so much? We enjoy the feedback, the validation, the interaction! It is not a bad thing.

You do self-validate; you think yourself worth posting all the time, sharing your problems and asking for others' opinions and help. Think of the people who do not think themselves worth other people's time and effort, those who are afraid to post?

We are never all one way or all another. There is much more depth to us than that. It is the depths we seek, that is the "whole" of us and you will understand and feel that eventually I think; you certainly seem to be working hard and well at it!
