I grew up in a semistrict religious context, and regardless of whether it was intended, I internalized that everything I did was a reflection of my righteousness and value as a human and even to a degree my worthiness to be accepted into heaven.
I've since stopped practicing that kind of religion, but I realized I have still been treating say my freelance work as a _moral_ question - if I do it right, I am good, if I mess up, or take too long, or there are bugs, my emotions still process that as if my eternal soul is at stake. Leading to, procrastination, stress, and withdrawing from communication because I'm afraid of punishment.
I had some really good conversations with clients lately, just being upfront about my fears of blowing timelines and admitting to withdrawing, and they were very understanding and to hear them acknowledge that this stuff is hard and that I was doing a good job was massively motivating.
Hopefully most people don't have this issue, but if you do, it was very relieving to even just realize this is what I was doing, and am working with a really good therapist and a business coach to process and work through it, and I'm already seeing a lot less stress as a result.
