Help with stress and anxiety

Em
So school is coming up and I attend a college prep high school so it's very hard. I have piles of homework due to first day and im so stressed out about doing it, I have to finish it and babysit for the next two weeks. I have SO much anxiety that I won't finish and I am super stressed about it. Headaches are NONSTOP. Any suggestions to help ease this? Xoxo
