First time here !!

Hi all,Well, before I  start, I would like to say Thank you to everyone for sharing their experiences , as they go through BC. To give a little background about myself, I am 25 yrs old, and was diagnosed early this year (can't wait for 2011 to get over, and close the doors on it !!!), I got no family history and it was shocking to hear the news, just like it is for everyone. Anyways, Doc was surprised too, and he did a genetic testing, and it came out to be in my genes (BRCA1 Mutation),. My mom was tested, but she was -ve. Anyways, I had to go through mastectomy (since was I at high risk of reoccurrence, due to my age and genes mutation). I had my surgery in March, and started my chemo in 2 weeks after surgery. Had 6 sessions of chemo, finished on 30th June and was not suppos to get radiation, since I had only 1 lymph nodes effected, out of 14. My onc put me on the world famous Tomixfen. I startd working in Mid-oct, and now my Onc suggests that I through radiaton, as there is a new study and it shows it might help me in the future by reducing the chance of reoccurance by 3%. They left the option to us to decide if we want to go for it or not, and We decided to go for it, coz 10 yrs down the road, I don't want to regret, and have that  feeling of "I wish I had done radiation back then". So now I am undergoing radiation for 25 sittings, 10 mins each sitting. So far it's been going good (I have just have 3 sessions out of 25..). .. My over-all side effects from everything (chemo, Tomixfen , radiation etc) include a  lot of hot flushes, Mood-swings, hair loss (of course), my periods stopped while I was on chemo and hasn't come back yet(the last time I saw my onc, he said usually takes about a yr orso to come back). Does everyone feel the same? There's a lot of times I feel helpless with the way I react to things. My family and husband have been really supportive with everything, but I seems my mood swings are testing their patience now. Is there anything I can do about it? What things do I need to be careful about, as I go through radiation? (It is just a local radiation to the Rt Breast), I am working full time while going through radiation, is that ok? What else can I expect from everything overall?   When can I expect the hair to grow back to normal?I know this is a long posts, but due to my young age, and no family history, I am completely lost and need all the help I can...and what better place than this!I just pray to God, and wish that no one goes through this. Its been difficult and it continues to be, but with great family support and an awesome husband,  ...I have something positive to look at.Thanks all again, for reading and supporting - And Good Luck and best wishes to anyone and everyone who has a close one going through this.
