That absolutely sucks beyond all words and I'm so sorry that you have to go through this, especially during such an important time of your career/life 🙁. I'm going to echo Epilepsy365 and say that you most definitely should not deal with this alone and keep it all bottled up to yourself. If you're not comfortable with talking to a professional or close family member/friend, at least find a way to vent and let it all out somehow--be it on an anonymous forum, private twitter, journaling, venting it out on a letter then burning it, etc. Match Day is still a ways away and the emotional and mental toll of this situation being dragged out on your own until then would be even more devastating than finding some form of help.
I'm hoping that the fact that two strangers on the internet have already reached out to you to express concern is enough to help you realize how important it is that you take care of yourself during this whole process and seek the help that you need in order to do that.
