I found that sertraline (Zoloft) has been quite helpful for me, ymmv. But it's gotten me to where the depression my brain used to rationalize as "your deserved guilt and shame are the cause" is now more like "yeah, that just happens sometimes, no reason."

When I've talked to my kids about meds, the explanation that makes the most sense to me is that depression has you down in a hole that you can't climb out of. The right meds can be a ladder down in that hole. Now you have a way out, but you still have to do the climbing.

I'm definitely not saying "You shouldn't feel depressed." Not that you should, of course, but you feel what you feel. Whether there's a "reason" or not, it ultimately comes down to neurochemistry, and your inherited and/or learned-in-childhood neurochemistry isn't your fault.

Bipolar disorder is kind of severe by definition (mild cases are still impactful), but there's a milder version called cyclothymia or cyclothymic disorder. Depending on the person, it can be managed without medication, and a common comorbidity is ADHD.

A recent paper reads:

Cyclothymia seems to be often associated with coexisting ADHD symptoms, although this comorbidity is understudied.

The paper is called "Clinical characterization of coexisting ADHD symptoms in a sample of adults with cyclothymia: A preliminary observational study".

It says:

In our clinical sample, nearly half of cyclothymic adults present with ADHD symptoms.

That's a lot. I hope more papers come out soon.

I'll allow it.
