Should I drop my sorority after holding a position?

Before I served on my chapter's executive board I really didn't have any issues with my chapter holding other positions but, once I was on exec is when everything started. I have never been more judged or ridiculed by a group of women as I have serving on exec. I loved everything that I did in my position but I would leave every meeting feeling judged and made fun of. They made me feel less than in everything that I did and I felt like no one else saw what was going on. I am a sophomore/junior so I have time left in my chapter but, I put up with their bullying for so long that it has left me with a bad taste for the chapter I used to love so much. IDK what to do :/
