Hang in there! A huge part of the depression you are feeling is likely the toxin build-up. That part will get better.
You are also dealing with the huge life change that comes with starting D. It's okay to be depressed about that, really. We all had to mourn our lost lifestyle and our dying kidneys when we got to that point.
As for what to do until then...
Program an ipod, your phone, whatever, with several different playlists. You are going to be stuck in a chair for hours at a time, and you will feel more comfortable with something to distract yourself.
Organize a selection of books to read, games to play, movies to watch if you have a lap top. Get a lap throw, a comfy pillow, a tote bag for carrying it all, and anything else you might want for comfort, like headphones, sleep masks, etc.
How much do you know about the lab work and the meds?
www.kidneyschool.org has lots of useful info. The more you know, the faster you can get the best treatment possible. Remember, the first month can be physically rough, so if you know the information before you start, it's easier to figure out what they are doing and what can be done to make it better.
Check into the chat room on here, or any other chat room you enjoy. Connecting electronically isn't a perfect substitute for face to face meetings, but it's a lot better than talking to yourself...
Hold on, it's going to get better!
