I am sorry you are going through what you are at work. I hate pettiness in the workplace. I have always been fortunate to have great coworkers, except 2 jobs, one where I was hired as a manager, and another where they thought I was hired as a "spy". I continued to just be true to myself, and believe it or not, they eventually came around and some even apologized.
As far as the stigma of divorce goes. It is how you carry it. For example, if an overweight person carries themselves like they are confident and beautiful, she is viewed as the same. If a thinner person is obsessed with her flaws and had o self-confidence, people will see them.
I was a 27 year old with an infant and my husband left me for another woman. I never carried shame with my divorce. I didn't carry it with pride, it's not something one should be boastful for, but I carried all that I accomplished despite not having an intact family with pride. People did look at me and "admire" me for not letting it break me. If I didn't show shame in it, others didn't either.
I have also always been fortunate to have married friends who enjoyed having me as their 3rd, 5th, 7th wheel. They didn't push me to the outside, because I was still me, minus my spouse. Actually, everyone hated my spouse and were relieved to have me there without him. He is aragoant PIA, and no one likes that.
Your divorce is nothing to be ashamed of, it is not an affliction. Don't let it change the way you carry yourself, and others will look right past it. It doesn't define you.
