Probably fail as my headfuck at the moment but better to try and fail than not turn up.
I can't know whether or not you will fail; but I do know that its not all or nothing.
This isn't your last chance for success, so if you don't pass this time, just pick your ass up off the floor and start over. Most people don't have the kinds of obstacles to success that you are up against: CSA, depression, anger, anxiety. You can be proud of every little step forward. Just making it this far is a miracle, and there's more in store for you. Believe it.
