I lost my GF recently, I have my English exam in class so I can't do birthday skip school. TOMORROW is the last day of school, so the teachers are deciding to dumb leftover work TODAY to free up tomorrow. AKA, today is a horrible horrible day.
That doesn't make your life horrible. I had to go to school on my birthday, I had to take a English AND math assessment on that day, and I have a lot of work.
Get over it, it's not that bad.
(The GF thing is slightly bad, but you need to learn to get over it, move on.)
Either way...
Happy birthday OP :D
