Feeling taken advantage of

I feel so taken advantage of by many people in my life. It is like I am expected to be this wonderfully cheery person all the time and to be honest it gets old quickly. I have feelings, I have issues, I have problems. I am also one with feelings and expectations of my own. People just seem to skirt around the issues alot with me. Listen, I KNOW I am fat.. it isn't like one day I woke up weighing 260 lbs. It has slowly creeped on, over the last 14 years. Yes, I know this. Do I need a reminder of it when I am with you and grab a coke? When I watch you eat 2 bags of chips and bellyache about being fat yourself? NO! Do I need to hear crackpot jokes about me and being treated rudely in front of others? No! I get tired of people always 'teasing' me and calling me lazy. One thing I am not is lazy. I may not get up and exercise like a mad woman on a daily basis but I am not lazy by any means~
Thanks for letting me post.
