Cathy, the funny taste/coating in your mouth will go away within a weeks time -- I had the same thing. Within a month you'll start getting your enery back -- you won't need to take a nap every time you go up and down those stairs that I promise will get easier by the end of the week.
If you weren't a little depressed, I'd wonder about you. I'm sure depression is just the tip of the iceberg. I'm sure you're angry, scared, disappointed, confused, and everthing else in between. Just know that all this will pass, and you will recover and be happier than ever. The body image thing will improve as well. Scars will heal and if you don't want to wait until they do so on their own, you can always have anything and everything fixed! Any bulges that shouldn't be there will flatten out in time.
You've made it through the worst part, now it's time to sit back, let others take care of you and breathe, deep long breaths -- try to just relax a little. Things will get done, whether it's you who does them or not. And listen to the caregivers assigned to you. They know what you're going through and can provide lots of information you can't get anywhere else.
Take care and feel free to vent to anyone and everyone!
