I was diagnosed with depression and anxiety during chemo. My BC treatment put me into menopause too. I am still depressed and anxious, but don't have panic attacks, though I can feel my body trying occasionally. I've had them before so I know what they feel like.
I was put on antidepressants and I'm still on them. See a therapist as well. I'm on Letrozole now, and depression and anxiety are listed as side effects of that.
I was talking about it with my oncologist a few weeks ago. She agreed with me that it's hard to tell where the effects of being diagnosed with cancer, the treatment, menopause and Letrozole, started and stopped. It could be one, some or all of them. Plus of course we bring our own life luggage into the cancer shit show.
She's asked me to have a two month break from the AI so we sort out what's what. I'm to take notes for two months before, as well as during, and then hopefully we'll have a better idea of what to treat, the Letrozole side effects or menopause. Both of which have limited options with ER+ BC... But at least we'll know.
BC is a clusterf**k. You'll get through, but it's hard. Ask for help. There's no point suffering from debilitating panic and anxiety. This BC shiz is hard enough as it is! Who would you feel comfortable talking to? Your GP, or breastcare nurse? There's helplines too, so you could call the Cancer Council on 13 11 20 or BCNA on 1800 500 258 for some support and advice.
Hang in there. Big hug, K xox
