Feeling unwanted

So I don’t know what it is about today but I just feel so unwanted in my own house first my sister comes home doesn’t say a word to me what so ever and who knows why then she leaves and then my dad gets home and he brings food I help him Bring stuff in no words I sit down at the table he walks away to his room n closes the door after seeing me sitting at the table by myself I don’t know what to do anymore I help pay bills I take care of the animals and I clean the house and I still feel like I’m not wanted in my own house anymore
