For me - how to make fewer mistakes.
My ''mother'' said to me that I was ''always making mistakes'' - she did not have any additional ''wisdom'' to offer.
I do not remember how I responded to that comment, if at all

Obviously it stung me deeply as I still remember it

(I wish I could forget that and other things my primary ''caregivers'' said and did to me in early childhood, childhood, adolescence....

I still do make mistakes sometimes.

Believe me when I say I beat myself up very effectively for each mistake I make
Has anyone found a way to eliminate making any errors in their life? I would guess nobody has, since I do not think its possible for any human to be perfect.... so I guess the best I can do is not to beat myself up too long for every unintentional mistake or possibly less than ''kind'' word I may utter when triggered...… I really try not to do that and I think mostly I succeed (but not always) Does that make me a bad person who should be shunned? Permanently?

My internal snake who was ''born'' from abuse many many years ago would say that
yes it does make me a bad person and that even if I apologize for any wrong I have done or said, that is not ok, since I do not deserve to be forgiven, much less understood...
''I'' do not agree with my inner snake's proclamation
respect and empathy to all who are battling inner snakes or inner critics or any conflict in themselves or any relationship and the beast of depression.
As a few (many?) may know I am one of the (relatively few) people who cant tolerate meds. This doesn't make life at all easy for me in real life or sometimes online either (there are many reminders, and of course anxiety due to …. CPTSD... I could go on
