Anyone else who can't function in their 40s? Why is it so much worse now and what to do?

I got some book recommendations from another community to see what has been discovered about ADHD since I got diagnosed 20 years ago. I bought a few and they haven't been delivered yet. For example, I didn't know my auditory sensitivities and rejection sensitivities were associated until recently. Also, daydreaming apparently.

But right now I'm in my mid-40s and I can't function. The political situation in the US is dangerous, there are serious issues with ethics and safety at my job that would have never been as prevalent when I started 20 years ago, there are pedophiles and people who protect them represented by half the population. So at this point, people scare me, I feel alone, and I think everyone else is nuts. You all know what they say about that.

With everything going on and my inability to handle basic tasks, I feel like I'm going nuts. It could cause trouble with my job soon. Any basic additional everyday problem is a major issue I can't handle. I can't focus at all, I can't do any hobby with decision paralysis, my anxiety is through the roof, and ADHD is ruining my life.

I'm too old to add more amphetamine s to my dosage. What can I do? Would a therapist be able to even do anything here?

Do employee assistance programs help?
