So my mom is almost 58..She has always been a lot of fun but a respectable person..She no longer works due to suffering with COPD...

Cut a long story short my mom seems to have a massive personality change..She is very angry most of the time.She has to control everything & god forbid who goes against her...She has an extremely short fuse to the point even her grandchildren are noticing..She had a hysterectomy 8 years ago so it's not the start of menopause..My siblings and I have tried speaking to her kindly about her behavior but she just blows up and accuses us of attacking her..

I guess what I'm asking is has anyone gone through this with a parent?? Was there a reason or did you manage to get them checked by a doctor?? We are so worried as to what has changed our mother from a funny kind honest person to a vicious bitter person with a tongue like razor blades??
