Being a survivor, I would like to share with you some information that I hope will be helpful to you.
Get as much information as you can handle about breast cancer. Although it can be overwhelming, the best defense is offense. Scope out the websites, do your research, see what type of treatment is available to you, for the stage of cancer you have been diagnosised with. This will help you understand what the doctors are talking about when they tell you their protocol on how to treat your cancer. Also, you can interject with information you have and ask if that type of treatment is available to you.
Get online and talk to other girls, join support groups. I found that talking to other girls about different stages of my treatment was very helpful. Go on www.LuvYourGirls facebook page and put questions out there to other woman, to see what they experienced during certain test. What experience was the worst or the best for them. Sharing and networking is so important.
When you go to your doctor appointments, always try to have someone there with you. There is so much information given, you probably will not be able to absorbe it all. Having a extra set of ears and its nice to have the emotional support as well.
When you are going to have certain procedures, ask the healthcare person what it entails. Could there be any allergic reactions to medicines they will inject into you. The most important of question is why? Why does the test need to be done?
When preparing for chemotherapy, drink tons of water (or liquid) to help flush out the poison they are putting into your body. 
If your chemotherapy is scheduled right after a meal. Try to eat light right before the time of the chemotherapy because your tummy can be unsettled with the medicines they are given. Gets lots of rest, don't over do it. Guess what the dust bunnies will have to wait.
I found that sometimes its not good to eat what you are craving, especially if your tummy is not doing so well. Best to eat softer foods, less fatty. I couldn't even eat a coconut fruit pop. The fat content in it felt like a thick crisco on my tongue.
If you are going to get a wig, have fun with it. Go blonde, brunette or pink. Go with a style you normally wouldn't wear. When you can finally look at yourself, then leave the wig, hats and scarves behind, and be proud, show the world that you survived.
I always felt like I wanted to scream. Its okay to scream into a pillow.
Its okay to feel sorry for yourself. 
Do not feel like you have to put a front on for people. If people ask you how you are doing, be truthful. Sometimes woman tend to try and be brave, if you want to scream, then so do.
This is your personal journey. Whatever makes you comfortable, do it. Wear pajamas all day. Don't take a shower if you don't feel like. I went for days without taking one, and I didn't care. If you have fatigue, relax, your energy will come back. It might take awhile. You might get frustrated, when all you want to do is your everyday chores, and showering and putting on your clothes can wipe you out. Forget about even thinking of food shopping, let someone else do it for you.
While recoverying, listen to music that will make you feel good, something that comforts you, something that helps nuture your soul. Gradually work up your energy level, it can take months. Mine took three good years due to all the surgeries I had. Give it time. I am one of those people who wants to feel better instantly. I had too much to do to be confined, but I had no choice, my body was healing on its own time. I thought that I was never going to have the same energy level again, but eventually my energy did come back. I am back with a vengance.
I was prescribed Tamoxifen for five years, and asked what if any other medicines were available to someone who was premenopausal, there were not any alternatives for me. I had some aching issues in my legs, I was told Tamoxifen does not make your legs or hips throb, but I read in the Nurse Practioner's handbook, and it was stated as one of the possible side affects. This is what I am talking about, being your own advocate. Do not accept an answer that you are not happy with. Go further, and check it out, do some research.
Through it all I wanted to survive. I wanted to show cancer that it was not going to beat me. I wanted to feel like my old self again. I wanted wake up from this terrible nightmare and see the sun again. I did, it took awhile but I made it and am proud to be a survivor.
