re-pledging...is this a thing?

Hey all,

So my story is a little bit complicated but I will try to keep it brief. Due to some internal issues, after already becoming a sister of a sorority, I had to resign from the sorority. Let me explain a little bit. I was recruited, became a sister, I was even secretary for a while. Unfortunately due to some personal issues, I had to put sorority life on the back burner and certain people didn't like it.
I turned in my badge and formally resigned. Now I am back on my own two feet and REALLY missing my sisters and the feeling of sisterhood. Is it possible for me to go back to my sorority or will I have to pledge again all over? I'm willing to re-pledge but there's so much involved (big sister choice even though I already had one) and other issues internally.
Have any of you left your sorority and RE-joined?
