Getting Tired of It

So my friend from high school who has been treating my sister and i terribly calls me to say that our group of friends are going bowling this weekend and has invited us along but the problem is and this is where i need to get angry, she tells me her car is full, and we need to find our own ride . So i'm thinking ok why wouldnt she want to take me and my sister? I take it we're nothing but two losers? I dont know why i keep putting up with it but for some reason i do. I just want to leave this town and move on somewhere else. I always felt compassion for my friends asked how they were, whats going on in their lives, i've always been on their side, been loyal to them and this is how my sister and i get thanks for . I'm not going to let it bother me, I rather hang out with my sister anyway, shes more of a friend then anyone i ever know. I do feel more lonely than i have before though. The people i went to school with or became friends with, i know they just feel sorry for me. Its called pity, thats what they have for me. I may not have the perfect hair or body but i do have feelings, looks shouldnt be an issue. i have confronted those about how i felt and it just went in one ear and out the other.
