It's wonderful that you can "explain" your personality and self by medically-acceptable (diagnosed) terms, such as "Mania", "Depression" "ADHD", etc.

But I would like to know, genuinely, compassionately and caringly,
HOW DO YOU REALLY FEEL?

Are you happy, joyful, content OR
(I hope so),
Or are more concerned about how others (perceive) or want to (diagnose) you.
I'm sorry (apparently, it seems) you are struggling with "mental illness" -

I don't believe there's a single person in this world, that does not have some personality characteristic,
that could NOT be described by a medical term.
E.G. We all experience "ADHD", even before there was such a medical term.
(ADHD was called an expected response to (what we perceive as being) stressful...
Sadness aka "depression" is an expected response when life doesn't go the way we want it to, etc.

Anyway, I just wanted to ask (how you feel), and I'm hoping
(praying, if I'm allowed to use that term here),
that you feel some peace and joy today...
because that's all that really matters.

Btw, I often feel, so many of the symptoms you describe,
but I also know, all of those symptoms are "normal",
based on life events,
until they cause you to do things that are unhealthy
or that you did not want to do.

Said another way,
Do you have reason(s) to feel irritable? Is something(s) in your life wrong, that you can fix?
Or is the irritability, just a symptom of something very wrong (chemical imbalance, etc.) of your physical body (not emotions),
and in no way appropriately related to the situation?

Btw, I'm always "irritable" when I'm tired (lacking sleep) or in physical pain, but symptom goes away when those things are corrected.
I've been lacking sleep for a very long time, therefore I guess you can say, I too, am always irritable...
But I really am not,
my inner personality "used to be" very patient (not irritable).
I'm sure any doctor, would love to treat MY irritability, but I would rather treat the cause(s).

You sound like a very intelligent & educated person (compliment),
but I still want to know HOW YOU FEEL RIGHT NOW?

Probably "annoyed" by my long post- LOL (just kidding).
