Do we really feel worthy or unworthy? That's a thought, not a feeling, right? I think what we feel is shame or disappointment or anger or grief, and then we think "if I feel these negative things I must be unworthy". Maybe it's a habit ingrained in us to think "I am unworthy", so it's hard to kick, but we don't have to think it. We could just think "now I feel shame" or whatever it is. And the opposite of thinking you are unworthy doesn't have to be thinking you are worthy. That kind of sets up a cycle where you'll always have to be feeling one or the other, fighting against the one and struggling for the other. You can't tie worthiness to getting the best or even getting anything. Because we will always make mistakes, and we can't always get what we want. Nobody gets everything, and some hardly get anything. If we see everything in terms of unworthy and worthy then we'll always be setting ourselves up, judging ourselves for the inevitable disappointments and losses. And we'll be thinking it about others too, that this other person has lots of money and a great job, he must be worthier than I am, while that person lives in the gutter, he's way less worthy than I am. The rich person may secretly run a Colombian cocaine farm and the gutter person may have been a WWI hero, for all we know. I think all that we can reasonably say to ourselves is "I try my best, sometimes it isn't good enough, usually it is."
I'm glad you posted this topic, it really made me think.
