HELP!!!

Hi everyone, i am very new to this ( computing ) not sure i am doing it right, anyway since my last blog i have seen the oncologist and i am in a bigger mess than when i was first diagnosed. I have  got grade 1 stage 2 hormone recepter pos with 1 out of 14 nodes involved, i was told this was the best type of cancer to have ,but it was left up to me to decide if i have chemo or not as the cancer in the node was only 2mm , anything under that and they dont offer you it , the oncologist said i would probably get the same outcome as chemo by having radiotherapy,tamoxafin, and zoladex injectionsso i decided to go that route , now i am terrified i have made the wrong decision ijust wish they could say that yes you do or no you don't need it , don't know what to do , has anybody got any ideas how i can be at peace with my decision or should i go down the chemo route i am really confused ?
