A therapist probably wouldn’t hurt to give a try.
You could also take stock of sources of stress in your life, especially any that have emerged/increased in intensity in the last few months. At my previous job, my anxiety took a massive spike due to a crazy boss, layoffs hanging over everyone’s heads and an increasing workload. Even on anxiety meds, I was getting massive headaches on a daily basis and would spend hours on the verge of being ill from it. Once I got laid off, the anxiety went back down to my more manageable baseline, and the medication became a lot more effective for managing it.
Obviously, just entirely leaving the situation isn’t a great option for everyone (heck, I lost the best paid job I ever had in the process, which wasn’t great), but even if that isn’t feasible, it might give you some insight into how you might mitigate the issue.
Also, keep on going when treatments don’t work. There’s no magic bullet here that works for everyone, so while it can be frustrating, keep trying things until you land on something that does the trick for you.
The Democrats have cried about “the most important election of our lives” too many times, and people tuned it out. For people crying how terrifying a Trump presidency was going to be, their actions told voters that they would be happy to let this happen and keep working with the same individuals they told them would end democracy, and so far, they continue to work with the Republicans, with a very few conspicuous exceptions.
People warned the Democrats they could only run that play so many times before it no longer worked, yet they decided to stick with it anyway. If the Democrats wanted to win, they needed to have run a very different campaign, if not a different candidate.
