Imsonia attacking me ..

That is why i don't like exam week. When I'm too stress, I will not have enough sleep and it will keep me worried.. Can anyone tell me how to cure this disease?? I got it since I was in secondary school.. Sometimes I couldn't sleep until morning and I have to force myself to close my eyes and fall asleep..What a pity right?? I need ENOUGH SLEEP to stay active with my routine..GOD,help me and give me the strength..AMEN!!
