I think your students value you for your wisdom and not for your appearance, even if they are in a different camp. And I don't understand how someone can be fired for being too heavy. Moreover, you are struggling with a problem that requires a lot of courage and willpower. I started many times and then stopped many times along the way. I would not say that I love diets. It sucks. But I try to work on myself again because I know that self-development is the key to success. Every person has the right to respect and dignity, regardless of their physical parameters. I am currently studying research papers at https://gradesfixer.com/ in postgraduate because the most popular academic fields are collected here. I specialize in the social sciences and want to protect the interests of those who suffer from social prejudice.
