Every day is so hard

All i do is lay in bed or on the lounge and thats all i want to do i dont even like leaving the house. I am going crazy i know it. I know something is wrong with me i have to go back to the doctor i think and every1 has been telling me 2 get some help maybe i do need  it. Just wish i could sort out this work situation
