Welcome to the online network.You have come to the right place for assistance in getting over the hurdle in front of you at the moment:). I was diagnosed almost 18 months ago now.My tumour was considered small at just under 2 cm.It was also grade 2. I take Tamoxifen every day,and in the beginning,I did have some side effects.Slight nausea,hot flushes,and moodiness.My oncologist at RPA in Sydney,encouraged me to persevere with it,as side effects with Tamoxifen are almost always short lived.As time goes on your body adjusts.Of course there are always going to be a small number of women for whom Tamoxifen doesn't agree,but even in those circumstances,doctors can prescribe medication to help.Some ladies on here take a very mild anti depressant called Effexor which they say seems to help.I encourage you to persevere,as it is very early days for you.Perhaps you are still in shock from your initial diagnosis,and having 3 young children,doesn't always allow you to take the time you need to really come to terms with a diagnosis of BC.Try to remember,that Breast cancer caught so early as yours,has a VERYgood prognosis.The MAJORITY of women with BC go on to lead perfectly normal lives,and it never comes back.Please stay connected on here.I think you will find it very healing to chat with others in a similiar position as yourself,and there are many ladies on here that have had varying degrees of depression along with their BC diagnosis.If you feel that you can't go on taking Tamoxifen,make an appointment with your doctor and tell them how it is making you feel.I am sure they will be helpful.Sending a big cyber hug your way:):) xxxRobyn
