Just wondering why your appeal was late? If I was in that position I would not have delayed the appeal.
I believe that if you have a significant problem that is contributing to this, then showing the committee that you are taking steps to resolve it is your best bet. Usually with most issues it can be evidenced by visiting a counsellor.
So telling your educational advisor
1. your problems
2. what you will do to resolve them
3. asking advice about your studies and progression
Should be enough for you to convince the committee
