Delicious, it seems like you have already made your decision; however, this is some last minute advice. I'm not sure what year you are since, but you said you've held an office for two years which means you've been in your chapter for at least 2 1/2 to 3 years. Even though you're not eligible to go alum, have you thought to try to contact your IHQ? There's always exceptions...
I'm sorry things did not work out for you.
