So I have ADD/ADHD as well.
I am always happy. Depression is not a part of ADD.ADHD.
You do not have to be this way and you can beat it.
>I also feel very phylosofical quite often with deep thoughts
I very rarely have deep thoughts.
Or if I do, I don't care very much about them desu.
It's real, but it's beatable. YOu don't need drugs to beat it. Just willpower.
One of the symptoms is you have bad short term memory, because you're always thinking, thinking about work, thinking about this, or that.
So you're not focused on stuff that isn't 'essential' or 'important'
This can be countered. Example, force yourself to only put your car keys in one spot, you won't absentmidnley leave them somewhere while thinking about work, and lose them.
Sounds like autism, I never got diagnosed, but I have not really an inability to connect with people, I work sales, and I'm very good, more a lack of desire.
I simply don't care to connect with anyone or even do basic stuff like say hello unless they intrest me or are a customer.
I also don't care at all about what others think of me, unless customers. probably also ties into autism, maybe it's related to ADD
tl;dr: You can beat ADD/ADHD with simple willpower.
The only negative effects are lack of focus on mundane tasks, willpower will beat that.
