Can someone help me figure this one out?

I have either major depressive disorder or bipolar 2,

AND I have either ADHD or GAD.

Or do I have all 4?

It's confusing!

So like... anything, medication, kind of therapy, whatever, that either only works for one or the other, or better yet, makes one better and one worse, could really help me narrow things down.

For instance, I don't know that the same treatments for MDD work for bipolar 2's depressive phases.

And I really, really am struggling to figure out whether I have anxiety or ADHD.

Stimulants cause unacceptable panic/anxiety, but they can definitely also help me actually focus and get things done.

I do SNRI for MDD/GAD... can't live with that.

But I also do lamotrigine(bipolar stabilizer) which seems to help!

I know I should take this to the medical professional.  But I tried that.  Now I'm taking it to you.
