advice?

hello! sorry if i seem awkward, im new here, but...

i am not professionally diagnosed, but i have known about my DDNOS since summer of 2014. my question regards the first alter that i discovered when i found out i had it, and things surrounding him

this alters name is taylor. he was originally very mean and very angry, and i didnt like him, but he very quickly mellowed out after i became aware of him. the problem lies not with him, but another alter that formed later on because of him, and this alter is named brier

brier formed out of taylors personality change, so brier is basically what taylor used to be. brier is angry, vindictive, manipulative, and cold. none of us like it at all, and whenever it takes control it has to bully taylor into cofronting with it, since it cant front on its own anymore. brier and taylor are also linked in the sense that i cant get rid of brier because something bad will happen to taylor if i do

a couple months ago, i managed to push brier back. it passed out and i took the chance to seal it in suspended animation so it couldnt do any more harm. it's still there in this white void area i dont ever remember making in the headspace, but i am forever scared of the day that brier breaks out of confinement. what should i do if it breaks out again? it has been proven to be stronger than me when im not exerting myself, as it has sealed me and other alters back multiple times, even knocking me out once... i dont want to hurt taylor, i dont know what to do about this
