Stress

it's just the begining of the year, and i am already stress out about some of my AP classes. especially my government class, i have absolutely no idea how the government function in United Statea and when it is time to write an essay about it, i am clueless. so yesterday i check on my grade, i cry. it terrify me. i think from now on i will study every night, but the problem is i have to work on certain days and it is impossible for me to study while working. i feel like i am hopeless, and i am scared to take my next test and fail it again. i really feel like my life is a mess now.
