Do you think there is probably something about me that makes people just not care about me?

Im sorry. Thats not good to feel that way. My personal experiance with feeling uncared for or invisiable was, I had to learn to love myself first. Try doing something for yourself atleast once a week. Paint your toenails. Watch your favorite movie. Walk around your house naked. lol. weird but it works. CLOSE UR BLINDS! Send yourself flowers. and in the little note write this " Hello Beautiful. You are perfect the way you are. Dont let anyone make you feel different. " When you love you, you gain confidance and others opinions dont matter as much. here... Have an e-hug.
