I do follow what you're saying, and I've been there myself. I just tend to view things differently now (and hopefully I'm not deluding myself with this belief).
There's nothing wrong with emotions and feeling things. I just wonder that it has to affect WHO you are. If you accept who you are, and that you are neither good or bad, you just are - moment based.
It's rare for people to feel "worthy", even when they've worked hard for something. Shouldn't the opposite be just as difficult to feel? Why on earth should we feel "unworthy"?
That doesn't unplug from feelings of attainment or shame, when due, but I believe it can calm the extremes. Yin and yang in balance and harmony.
