You can be your authentic self and not bear too much of your soul. No matter what you argue, it's ego you're protecting. I can show my true self on this forum and still not give up the safety of my life away from this forum.
When talking about being authentic, we're not talking about sharing your phone number, address, pictures of yourself, location you live at and specific stories about your life. You can be genuine and honest without those things.
So far, I only see armour in all your posts. You can't convince me that constantly referring to your posts here as some false persona of you, and saying you only let a few people here see the true you, people who are "worth it", isn't about protection of ego and rejection.
If you want to convince me you are trying to conserve energy, I won't believe that either. You put a lot of energy into this place. Wasted energy. There's no telling what you could have accomplished in all the time you've spent on here defending your ego, and trying to make a bunch of strangers understand you.
Would you say you're egotistical or no?
