I barely have any of this in my life, but I know it's true- Your desire to be valued is important and meant to be filled, we don't only need God and God is not enough, we are meant to go together, people are meant to share their life, and in relationships in our life we're not meant to question whether they value and appreciate us BECAUSE= they're supposed to TELL us, and not just once, it's a "law" of relationship.
I'm very sorry you're feeling this way, I know how it feels too, it is very hard. No matter the how many people who are going through it and no matter how many people accept it in their life even a little, they should know deep down it's not right, I know that a lot because I think logically or something.
People have needs, and it's not wrong in any way in a very important perspective. But some people treat it like it's wrong and like you're just really broken. You are broken in another way, but we also simply have needs, and it doesn't make us broken, but a deeper kind of thing of missing something supposed to have, meant to have. Just like going to the doctor, or being unhealthy, an unhealthy person is more told they have needs, they're not told they're sick, but just needing. So know you have a need, everyone needs love, affirmation, to be appreciated, and to be valued is very important. Like me you don't even have to have it much at all, to know that that is true.
It is always good to hear from God personally about where you're at with self-identity stuff, He knows deep things and can give revelation of deeper thoughts below in hearts, and he likes to grow hearts, whenever struggling in a distressed way from the cores of value. I have experienced it a lot and it has grown me a ton, I still have forever to go but that's okay.
The world is full of wisdom about this stuff and even some hard conviction, but the green alive life-words to your own heart are what matters, I hate having to hear a bunch of people convicting everyone of their identity problems when that's not even where me and most are at I think, and they just keep saying it over and over when that's not enough, knowledge and conviction are very not always strong enough by themselves to take on bad stuff. And I think most us Christians (including me) rather like to put their emotional stuff in their air, than actually talk TO eachother and receive something in our heart. And when I have done that it is so real, whenever people do that it is always really cool, shakes personal planets

God bless, take care <3
