It's useful if you want to avoid a major social "faux pas", a mistake that would have significant consequences. Like making an edgy joke towards an important person, or when it's grossly inappropiate. Having a bit of self-doubt and restraint
there is good, it saves you from the consequences of that mistake.
But having
too much can well, get to the point where you're not able to talk confidently enough to build good social rapport, and feel insecure in social spaces.
I came upon this question a few years ago and I never really reached a satisfying answer. Self-denying and self-destructive thoughts pop into my head all of the time and I sort of lump most of them under the umbrella of "self-doubt." I figure that if I ignore all doubt in my head I would be a lot happier. This brings about the question, is there a time when self-doubt is useful? Most definitely when one is pondering to do something stupid, the rational might is right to butt in and make itself known.
So, there are some moments where self-doubt is useful, but there are many moments where its the personality's way of sabotaging itself. How do you identify when it is one way or the other? What is your experience with this elusive character of self-doubt?
I'm really sorry to hear that you have so many self-destructive thoughts. They are hell.
I am not you, so take salt with this advice I'm about to give. I can only speak for myself, but I hope this provides at least
some degree of help. Something that helps
me a little bit at least with whatever few thoughts of those that I have (usually just a quick thought of "KILL YOURSELF" over some minor regret, to the point where my mind makes it blatantly obvious it's overreacting), is to know that these thoughts do not come from any logical finding or genuine contemplation: but from pain. they are the cognitive equivalent of shouting "OUCH" when you get a wound.
Know that you are
not your thoughts. no matter how many of them you may have. You get to decide which thoughts of yours you agree with, even if you can't control what thoughts you're having at all. I've heard it described like a river. You can just pick out whichever thoughts out of this river that you want to agree with, no matter how much other stuff is flowing past.
