My Mum has been on tamoxifen for over a year now after her end with breast cancer. I'm just struggling with the side effects it's bringing. Since she's been taking them she's been very stand off ish. She has bad mood swings and it can make very very nasty towards me. I try to sympathise because of the purpose of them but am finding it really hard. She's almost a different person, hardly makes conversation, doesn't pay much interest towards me. Her comments can be nasty and irrelivent. Before she started taking them we had s close bond and I just feel like she can sometimes be s totally different person. Any suggestions on how I could help or any advice would be really appreciated. I love my mum and just want her back toher normal self.
