Is this as good as it gets?

I have been on Tamoxifen for about 8 weeks now.....I haven't really noticed any change in my mood......I already have a short fuse! But I do think it is from the whole ordeal of breast cancer and it's treatments.....I now find myself saying exactly what I think and feel, with no remorse!....While I find I am patient with most  things....the simplest of things will cause me to get flustered....and then I have a hot flash! grrr.....I find myself fed up with the trivial things in life and on the news etc.....It's like get a grip people! ......Our bodies and  minds have been through Hell and back, but we still expect too much of ourselves.....to be 'normal'....to behave the way society, friends and family one day at a time....if it's a bad day, it's a bad day... I do believe in time, as we get further away from this experience, it will get better....meanwhile we have to ride the wave and our loved ones will have to dive for cover! LOL!......I hope you heal well from your fall.....I often think while I'm driving, what if the airbags go off and hit me in the chest? I'm screwed! Bye bye expanders!  Love and llight - Tracy
