<human>: Can you condense the text into a few key points?

Hello r/relationship. This is my first post. I'm not sure where else to turn for advice on how to approach my parents about some bad news about this semester at school. I'm currently out on the East coast in my last semester for my B.S. degree. However, I already know that I won't be passing all of my classes... Like, more than likely none of them. 

It is quite a lengthy story, but this is related to a time I was sexually assaulted on campus back in 2011. I had a horrible (albeit even more traumatizing of an experience than the assault nearly) time with my school's handling of the situation, specifically the campus police. I have learned recently that the symptoms that have been preventing me from attending class are related to a PTSD diagnosis I now carry. 

Bottom line, I couldn't handle being on that campus. Anywhere near either if possible. 

My close family, bf of 3 years, and close friends just found out about the sexual assault less than 6 months ago. I just sought out professional help a month ago. 

The scary part is this..... my parents still don't know I haven't been in class basically all this semester. Couldn't handle it. My school is NOT cheap. My parents have to seriously budget to afford it. Not to mention, I'm a "super senior" or someone who graduates in 4.5 semesters; i.e. an extra 15,000+ for the extra 1 semester as it is. For what? Nothing. I'm so ashamed I couldn't pull it together faster or better or at the very fucking least could have had the balls to say "help" before this all got out of control. That's my real concern there. My parents are the most amazing people and are so supportive, loving, open, etc., and would have done anything for me when it happened. I just couldn't accept it was real and instead of dealing with it or anything else, I slept, lurked on Reddit, and did... nothing. 

I don't know how to tell them the truth about school.
<bot>: I will more than likely be wasting a semester's worth of my dad's money due to lacking the coping skills to manage PTSD symptoms. How to tell them I fucked up?
