I would love to help you, but I am going to sleep.
I will just give a brief advice right now, and then perhaps I will make a longer post.
Just take it calmly for the time being.
Try to relax and don't rush the situation.
Finish your finals week, and with a calm mind you will be best for taking the decision.
As said in Kung Fu Panda, your mind is like agitated water, if you allow it to settle the answer becomes clear.
That's all for now, then I will post about relationships and such. Good luck with the tests!
