wow!! i have to go read your profiile/bio now!!
i agree with Mandy, sometimes we get so stuck in that recorded mental message of 'ugh i dont want to do ANYTHING" that we dont do anything... particularly after long periods of forced to not do anything.
To elaborate on Mandy's suggestion, pick even one thing that you used to love. think about how it made you feel when you did it and really think about how you want to have that feeling again! if doing it to the fullest extent isnt possible now, break it down into smaller pieces.
For example, if you used to enjoy running 6 miles a day (haha sorry i have to laugh at myself for this example because i so dont run and it's on my live 'to do' list!)
think about how you would feel when you got dressed, how you would get kind of excited that you were going to have time for YOU, how you felt starting out, how your body felt, how it felt half way through when you would start to sweat and get warm! remember how you felt at the end when you would be out of breath but with an extra spring in your step and smile on your face! and the shower after when you are cooling off and you feel SO CLEAN when you get dressed because you have rid your body of all kinds of toxins!!
now! once you do that for a while... take the baby steps... just get dressed in the gear and wear it around the house, do this for an hour a day as if you had gone running and do the cool down/shower part too!
then work your way to walking for 15 minutes during the middle of that hour around the neighborhood or somewhere and think about how that makes you feel a little better than just 'being' in the clothes
and so one.. work you way up to it little by little! the smaller actions will entice you into the bigger actions!!
of course you dont have to do this with running, but i would suggest you pick something you really enjoyed previously so you can draw on the positive memory! and this is just a really tangible example
let us know what you choose to do to motivate yourself!!
oh! you can also set rewards for yourself for doing little things, even if you think it's silly. like setting up a 'chore board' for yourself with gold stars! laugh at yourself! it's ok! and share with us so we can cheer you on and laugh with you
there is an article here (i HAVE to find it, it's the 2nd time i have wnated to reference it today!) that talks about the 'did do' list intead of a 'to do' list so that at the end of the day make a list of your accomplishments! this helps you end the day on a positive note of what you WERE able to do! and i bet week to week it grows into a bigger and bigger list
sorry for such a long post, i just felt inspired LOL
