I think it is good to keep yourself busy and active. I have been at that stage of giving up and doing nothing, staying in bed and getting really depressed.
I have to make myself go out everyday, whether it be for a walk somewhere or in to my town to have a coffee, anything. I really think this is the best thing as sitting around doing nothing only gives you time to think about your feelings making you worse, becoming more inactive and depressed.
Like totherescue21 said, making a weekly plan can really help as it gives you things to look forward to. I also think getting out helps as well, see life around you. I would say not to try and do to much at once though, it is also good to have relaxed days as well.
