My core belief of low self esteem and generalized self-negation has been pretty bad, and I've been very hard on myself for many many years. When I share these ideas, its not from some elevated platform, its because I have and often still do struggle with this stuff, sometimes everyday.
If I am being overly negative about myself, I feel its the mind/power/will of my abusers and/or the net effect of my abuse...still abusing me. Just like self sabotage.
This is distinctly different from self-hazing, where I call my own BS, my own tendency to chicken out, or dodge the bullet, or forget I am a perpetual student of life, and there is limitless stuff to learn.
There's also the thing with modesty, and the stuff we're taught/conditioned about bragging. If I give myself props for something I have done eg: quitting coffee/caffine, that's not bragging. If I give myself props for having stuck it out in life against the odds, and faced the challenge of healing, that's not bragging either.
Since you're alive, got a good T, are writing your diary (that's huge) and brave enough to share like you did here, you got plenty of positive things to give yourself props for, IMO. Not to mention, patience dealing with me! LOL Good god, give yourself a pat on the back right now for that one - jeepers...
Will Rogers said it best: "If you done it, it ain't bragging". :-)
