Constantly ignored

Had a friend come over. Having fun baking together. Suddenly my more charismatic housemate comes in, mind you her and my friend have never spoken. Suddenly they are bffs and im getting sidelined and now when I try to enter the conversation I look like a dumbass or a loser. Its so exhausting why am I never a point of conversation for them, genuinely why do I even bother if im just gonna feel like shit in the end what's the point. 

Some people really just have a natural charm that can't be beat and others are stuck being weird freaks forever.
