hi, i have a good friend that slipped on the ice in february and hit her head. after going in the house, she couldn't figure out why her hands were bleeding. she had scraped them on the sidewalk. luckily, her kids were there and took her to the e.r. she had a concussion and to this day, still isn't herself. suffers from a lot of what you're feeling, no energy, no motivation, feeling lazy lazy lazy. not as sharp as she used to be. and overall, just not herself. her doctors say that sometimes, it just takes time (and lots of it) to get back to normal. but i know she's frustrated as you must be. i hope things start to turn around for you soon.
