Life after Tamoxifen

i stopped taking tamoxifen last July after 10 years, since then I have been feeling awful, don’t know if I am now finding out what it’s like to be menopausal or not as I feel I went through it ok after chemo and was told I was post menopausal whilst on tamoxifen, I am exhausted all the time even if I am blessed with a good night sleep although I’m not sure what that is anymore, my body aches and I hobbled about as though I’m older than my 57 years, I am quick tempered, anxious, have zero concentration and brain fog is worryingly bad. 
I went to my doctor about my sore leg and said about my anxiety etc and I somehow left with antidepressants and a form to register for physio, think he just did not want to deal with a what he thought hormonal woman, not sure where to go from here
