hi FlffyChic
what helped me a lot was finding things and activities i could smile about... pictures of kittens always got me... then i put a few up around the place, so i could remember the goal... to smile, to feel good..
there's other ways of encouraging yourself like little statements, affirmations put around in places you'll run into them and read them... even if you didnt read each time... the note/reminder/pic will help you remember the goal ... to smile and feel good inside...
try it awhile if you think it'll help? it takes time... positive energy has a snowball effect too..
and prayers and wishes for you and son...
