I don't know if this is of any help at all given i have no clue in this area, but thought i'd share something that helps me.
I've always struggled with the concept of a 'self', let alone my own. Today there is some kind of sense or resemblance of something there that is actually real & solid & good as my 'self' (although blurry), but i still don't really get it.
I remember talking to my therapist about it & how i wanted to learn the same things (self esteem/worth) & that i was guessing it started with believing in myself first, but there too was the same problem ..believing in what exactly & 'what is this self you speak of'? (the only idea i had was of a pretty crappy one)
He just asked me, 'What do you really want?'
And even though intellectually i knew exactly what he was asking, i'm embarassed to say i had no idea what he was going on about .. i had never allowed myself to go there before, or thought to. I mean ..what the hell is that suppose to mean anyway & what on earth does it have to do with anything?
After asking what do you mean, he said ..not what will make you feel better or you 'feel' like doing, or what you should or need to do, say etc. but what do YOU really want right now.
And i had absolutely no idea. I had thought everything that i had been doing was what i had wanted. But as it turned it, it was all just what no else had told me what to do or what i had decided for myself but not necessarily in line with what i had actually wanted. Mostly, when i really thought about it, it was all just what made sense to do or say.
So, after having no clue what that could be (no one had ever asked me that before), he advised to start small. And for me, that was, what do i really want to have for lunch?
His office was a 2 1/2 hour drive from my place & i would usually go through Maccas afterwards ..it was easy. But not what i really wanted. In fact i found it very easy to come up with many things that i didn't REALLY want but struggled to determine what i did.
In my usual dog with a bone style, i really wanted to figure this out & it took me about an hour into my drive home to realise what i did want, & i was starving by this time. What i really wanted was my favorite sandwich that would need to be made at home & after going to the supermarket first (which was known for being way too 'peopley' & especially from being so wiped after my appointment & the drive up & back). But i was curious about this process & wanted to give it a go & decided that is what i would do.
And i was surprised by the results. The hunger pains eased, the drive home flew, i didn't even think about going in the supermarket & before i knew it, i was home eating my sandwich ..& it felt good, the whole experience from the time i made the decision, felt really good. 'I' felt really good.
Now i don't know if i'm just particularly broken in this area or whether most people seem to get by without ever really having to think about it, probably a bit of both. But what i do know is this. Whenever i truly answer the question of what do i really want (to do or say or whatever) & live accordingly, all my areas of self worth, esteem or believing in myself, never seem to come into question. And the only times that i question or doubt myself or self loathing has crept in, is when i have lost sight of it.
I think that maybe developing self worth is up there with how to be happy. It's not something you can conjure up directly itself, but is rather a byproduct caused from doing something else, eg. when i do this i feel happy or when i do that i feel good about myself.
And for me, i feel good about myself & confident in what i'm doing whenever i am doing the things i need to do to answer the question 'what do i really want?'
Hope it helps.
