Feeling Low Moral

Business have been bad this two month and my Boss have given her remark about my branch sales drop and i'm feeling not just unwell but also stress to de max and i'm really feeling  low moral in my work.
And I find it hard to concentrate when working not just cos of the medicine I'm taking but also the pressure that i'm not preforming well in work or hard to stay awake while working and taking my medicine at the same time.
God please give me the power to overcome all problem i'm facing now and prove myself that I can do it even without  anyone help!
I'm loosing  the like in my job due to the dislike to my staff as they are older and hard to control and harder to teach in all way and that is making me so so tired just thinking  of my work .
I dun mind being busy but i can't stand feeling hopeless in everything i'm doing in my life.
Think that all i'm gonna write for today about my problem and feeling...pls follow me if you wanna know more about me or if you like me...see ya !!
