You may wish to bring some of these mental-health issues to the attention of your academic dean/the scholarship review committee/whoever would make the decision on your losing the scholarship, along with your therapist's contact info and possibly a letter from the therapist. Although there are academic-performance guidelines, the school may be able to work with you on this. Usually a school will NOT want to revoke a scholarship if a student demonstrates commitment and performance is impaired by other factors than simple "slacking off". Long-standing psychological trauma is a MAJOR other factor, and the fact that you're working on it with a professional shows a commitment to making your life better, and an ability to prioritize, that reflects well on you.

I was in a similar situation many years ago, and I know it's worrisome to think you're losing that educational chance on top of your other problems. But most schools really don't want to kick you when you're down; if they're committed to education they'll want to help you through this so that you can fulfill the promise they saw in you when they decided to give you the scholarship. Good luck.
