Anxiety with letrozole

This will be going on my 3rd week of letrozole. I only noticed mild night sweats the first few weeks. No big deal I’ve had those since I was 25. I’m 39 and recently diagnosed. Treatments all started just a month ago, so I’m super fresh! lol! Meds are Lupron, kisqali, and letrozole. I did fine with the first two, adding letrozole was fine until a few days ago. I can handle to crying outbursts and nights sweats, but the anxiety, agitation, and anger, no! I’m becoming borderline panic again. Panic attacks and anxiety is only brought on by meds. I’m not sleeping at night because I’m waking up with extreme anxiety borderline panic attack, and it’s miserable. I had an awful experience to a medication 9 years ago which the side effects were mental side effects. I had a panic attack for 6-8 hours a night for 8 months. I don’t like taking Xanax bc I cannot function so I held on tight for a terrible mental ride every night! I don’t wish for that to ever come back, but I’m getting very close to experiencing all of that again. I have terrible ptsd from all of that. And now I have a whole new ptsd.😫 anyways what did you all do to help or what meds did you find to help better? Do you think I even need this med? Waiting to hear back from MO sometime today, but I’m now all a mess of worry with this. I’m picking fights with my husband, snapping on my kids and random people. Don’t get me wrong, I don’t mind the snapping part only when I need it, it’s somewhat helpful since I’m a people pleaser trying to stop. lol. I’m trying to find the bright side of all of this. Ive been on lexapro for 17 years for depression, and since added busparione. I have propanol for anxiety, but don’t like to take that too much bc I already have a low bp, and Xanax when things are bad, but that literally makes me unstable, and can’t live like that! I need your help, advice , comfort, other meds that worked for you. Does this last forever on this med or does it get better. I’m on 2.5mg.
