i'm sure they care about you, maybe they're not quite good in showing it the way you want them to show you, but that doesn't mean that they don't love you. they are still taking care of you, giving you food, having you around, maybe it's also difficult for them to reach you because they don't know how they should do it, i dont know, i'm just telling you, dont give up, it might also be hard for them to handle things, but of course i dont know what happened but still <3
