What Causes Persistent Fatigue And Anxiety After An Oophorectomy?

Please help , I am 5 wks post op oophectomy . I had the surgery for pmdd , cyclical anxiety which lasted 5 days a month , I had for 15 year . Pre op I was on 75 mcg estradiol patches , estrogel and climaval and previously had had implants of estrogen and testosterone until they became available . In the early days I was under proffeser studd . I had injections of cetrotide to shut down my ovaries to see if this worked before surgeon was happy to go ahead . It did work . So went ahead . I am not having flushes or anything but I am so tired all the time and have the same kind of anxiety as before . What can I do please ? I am seeing my Gp on Friday as surgeon no longer needs to see me but I m worried she won t know what to do . Seems strange I m on less hormones after than before .
