I am so sorry you are feeling this way. let me tell you about my system and maybe it will give you some idea on how to help your self feel better.

my alters didnt question their existence and didnt need me to tell them that they existed. they already knew they existed simply because they walked, talked, played, cooked, cleaned, went to school, went to work, they knew what they could and could not do, they knew what they did for the body, their self and others inside the body and outside the body. they could think about their self and anything else... they could breath, if they put their hand on their heart they could feel the heart beating, they could eat, drink and go to the restroom.... everything in general that any other human being could.

my alters knew if they didnt exist then they would not be taking control to do their sense of agency, every time I dissociated,

in fact my alters didnt even call their selves "alters" to my alters they were complete individuals and functioned that way.

as for names my alters also didnt have a problem with being called the body name and also having their own names. they were this way all the body's life time. it was the normal. by that I mean I was DID before the age of 5 and I wasnt diagnosed until my 20's so everyone in my body including me grew up with more than one name and had no problem answering to the body name....

just like for example my daughter answers to her birth name (what the name is on her birth certificate that my wife and I chose for her through out my pregnancy) my daughter also has a native american name given to her at her naming ceremony with the tribe, and she has many nick names given to her by her teachers, relatives, friends and also one she chose for herself... and Im sure that as she goes through her school years there will be many more names that she will be called or nick named.

my point is that here in america its normal for children to have and answer to more than their one name. my alters never had a problem with names.

as for worth well others cant give you a "worth" a person and an alter isnt some commodity for sale, barter or steal or bargain.

worth is something you give your self. its one of these things where you decide for yourself if you are good or bad, whether you do things that you like or not like. whether you believe in yourself, trust your self, what things you do for yourself and others.

example my alter Rainy felt she was worth it because her job was to take control when ever I had my dissociation problems because of my trigger thunder storms. she would get us home safely, changed into warm clothing and a hot mug of hot chocolate and a sand which to warm us up with.

Red felt she had self worth because her job was dealing with anger issues that I could not handle and would dissociate because of anything that caused me to feel angry.

suggestion maybe you can sit down and write out all the different things that you do for your self and every one else, write out what you like to do, what you like to eat, what music you like.... all these things that gives a person the sense of their worth.

if you come across something that you do that you feel isnt worth it then all you need to do is not do that any more.

Rainy felt it wasnt worth it for her to brush her teeth so she didnt brush her teeth any more.
