I’m sorry about your pets…but I don’t think the school will reinstate your aid because of your pets…or their bills.
But you can try.
Right now, all you have is things you HOPE will improve your grades…none yet proven. Just be prepared if that is the decision of the appeals folks. They might suggest time off from their school…with courses taken at a CC to prove that you actually are able to handle these now. And yes…I realize your freshman year was better.
Your letter is OK…except that you don’t really have anything you have already done to show you can be more successful moving forward.
It’s worth a try…
