motivation

i don't know if this is something that meds can help me with, but i have no motivation to do anything. i am guessing it is a symptom of my depression, because it isn't always like this. i just lay in bed, trying to think of things to do, and moreso, trying to get myself to get up and do something, anything!
i had a goal of working out more, but i can barely get myself to the gym. i try, i really do. i went twice last week, but ended up staying for only 20 minutes. my mind was racing, and i had a sort of agoraphobic feeling.
when i leave the house i feel really lost and confused.
i just want to get better. i am not sure what else to do.
i am not looking forward to going back to work. thank god i have two weeks.
