I can't win....even at the gym

So I'm a fat person but I've been losing quite a bit of weight. When I wasn't working out it was "oh well she's so unhealthy she doesn't work out thats why" but at the gym the nanosecond I step foot in the weight training area, there are eye rolls and huffs and puffs and tons of staring. I can't stand it so now I'm stuck in the cardio section of the gym.

What the heck am I supposed to do? I feel like I can't win - can't do anything right. There's commentary when I'm not active and hissy fits when I am active!
