When you get a bc diagnosis,everything happens so quickly and it's scary and surreal.It's not until after surgery and results that we really begin to process what just happened.You've had to face your own mortality and had an amputation of a body part.Now throw in a drug with lots of side effects- of course you'd feel down. I became quite moody/teary/irritable when I started Tamoxifen and had bad hot flushes.After 3 months my oncologist put me on Endep 10mg which is a very low dose anti depressant for sleep and hot flushes.It really helped and no side effects( for me).I had tried Effexor but that drug left me semi conscious! We are all different.You may find talking to a psychologist helpful or even just blogging back here to vent your fears.We know what you've been through and can relate to your worries. I've had early bc twice. First time was in 2003(47yrs old) and then again in 2010.I had similar pathology to you.From my experience,it takes about 18mths or so to get abit of confidence back in your health.It is quite normal for you to feel worried but in time your fears will lessen.I'm fine now but always get abit anxious around mammo/ checkup time.Perhaps finding some quiet time for yourself might help?eg art therapy,meditation,yoga,walking.Time to look after YOU : ).
