Who took my brain?

Ugh. I just realized I did something I've never done in my whole life. I forgot an appointment with someone for the 2nd time in a week.

I guess there are contributing factors. We were having computer problems at work on Friday. I was being emailed by people about the problem faster than I could possibly post an explanation or address it. I forgot the first meeting in the rush of responding to that. Apologized profusely, called the person, and he was kind enough to reschedule.

And then I did it again. Just no-showed. A colleague pointed it out, which is so embarrassing. I made an excuse, but honestly, I'm mortified. I think wtih all those emails coming in, I got distracted and never got the appointment on my calendar apparently.

I've never had problems like these before cancer. I noticed it when I came back to work after chemotherapy. But that was back in early 2019, and I thought it would go away by now. My doctor put me on Adderall (ADD medicine), which mostly just helps me focus on what I'm doing. But I'm not dealing well with having to have multiple ideas in my mind at one time. For example, when I read something I can't seem to hold it in my brain long enough to write it down. It's really maddening at work, but I'm a professional and I've worked hard for my position. I could retire in 3 years, but I'm ambivalent about it.

I've not talked with anyone at work about this problem, because I find it embarrassing. I've been trying to switch to tasks that are less likely to be impacted by my this problem and reducing the tasks that require a lot of manipulation of mental contents. But that's difficult to do, because that's a large part of my job. So far no one has said anything about it, but I worry that I'm perceived as "over the hill" now because these slips are noticeable to other people.

I guess this system will attach a list below of the surgeries and medicines I've been on. I was recently switched from letrozole to Aromasin, 25 mg. Otherwise I'm off the Big Drugs. I thought "chemo brain" goes away within 2 years.

What gives with my brain? Any ideas and /or recommendations welcome. I'm kind of at my wit's end!
