Are fat people unattractive?

I am considered obese for my height. Most people would think overweight but not obese because of how fat deposits on my body. I have been on a diet and have tried exercising more. It can be difficult because I have hereditary asthma, seizures, and blood pressure problems which started my weight gain because I couldn't exercise as much until I found the right medicine for me and I was able to leave the hospital, but I am still trying. Someone posted on Facebook how fat people are unattractive and gross. The comments were so hateful. I've been diagnosed with an eating disorder, and it just fueled my disorder to the point where I was craving food real bad and wanted to revert back to binge eating because it made me so depressed. Is this really how everyone sees me? Like what's the point of actually trying to exercise if everyone I run across is mentally thinking I'm unattractive or gross. It's hard enough because I feel like I'm going to kill over when I try to exercise due to all my health problems which have gotten worse due to the weight gain that they caused.
