Tamoxifen - just started taking this again and it's really taking a toll on me. So tired of fighting

Just started taking this horrible drug again. Done 5 years now I need to do another 5! It’s really beating me this time. Very low mood, ovary pain, fatigue, joint pain,  not sleeping, and volcanic hot flushes. I’m so tired of fighting. 7 years of blood sweat and tears!
