I don't know the specifics here, but I have suggestions. You admit that you have problems and are getting help which is the first step. I think that apologizing to the people you have hurt individually and to your chapter as a whole is another important move. College is a time of learning and growth and part of that is making mistakes. If you show them that you are trying to repair the damage that you have done, your sorority sisters should stand by you.

Sarah, I recommend that you keep working on it. They will see the changes in you as you rebuild your character and reputation. Also remember to forgive yourself. Sometimes guilt and regret can cause people to return to old ways of doing things so let yourself off the hook. It drains you of energy that can be better spent repairing relationships and most importantly yourself.
