udacity - Misguided me to commit mistake to get myself trapped in the honor code for plagiarism

I have received the email for first plagiarism and it was under promotions section of mailbox and also it was Diwali week here in India and it went unnoticed.

However, inside the review comments for flagged content, there was link related to GitHub repository shared by mentor which I never referred .

Though I made changes asked by him in code area and resubmitted in a hurry thinking this is the only area needs to be updated.

Also , by that time I was not aware about the fact of there are only two warnings during the course duration.

Then once next review comments received , the mentor referred plagiarism for another repository which I agree that I have referred related to writeup of the project.

By that time , I tried to ask this in forum about this and I checked emails and found that there are two emails in promotions folder of my mailbox.?(Also second email says its final warning)

Why these emails are not marked important at first place if these can cost me full money of my lifetime savings? I was so panic and did not sleep for next two days.

Then I though may be I should change everything and so I deleted all the material uploaded and created everything from scratch (output was as expected) and tried to submit it again in this situations on Diwali day.
But again it did not allow me to do so( I asked Udacity team can to check all files available in my workspace of GPU in a ticket to cross-verify), and mentor told me to wait until this matter is resolved.

Since I was not aware about the severances of the mistakes I did unknowingly I appeal for the consideration and consider full scenario .(raised tickets since they don't have customer support)

Because, for the first time in my life I have invested this huge amount on learnings. And it will make my life upside down if I fail here. I was mentally depressed , had sucidal thoughts
thinking all of my lifetime savings are gone and felt sick .( I have all the reports of hospitalization in case required.)

Also there is no proper customer support of Udacity(Only email services available, which are so delayed and make it hell to wait for)

I need my money back( Though I wasted three months too before they throwing me out of course)
