Depression or ADD or addiction???

[Alyssa 13]

Like many, I treat my depression with adderall. But what does this depression mean exactly?  

Does this mean by some awful fate our brains were naturally born depressed, and then we got our ADD diagnosis, and then we were like wait this solves my depression too hell yeah! And self medicated?

does this mean that we never had ADD but really we just had depression, which cause ADD like symptoms? 

OR are we FEELING depressed because adderall addiction is screwing with the rewards system in our brains? 

^ which basically is our addiction speaking, telling us now that we have been depressed all along, and need the drug more than previously conceived. Right?

Is this depression ( whether natural or causes by adderall ) able to be solved WITHOUT medication??? 

to those who are still on it, what are your moods like?

To those who quit, do you feel you will always battle this depression?

are there any of you who have never felt depressed???

(i have been feeling insane these past week or two. I upped my dose to higher than before to lose some weight, and then it pissed me off so I quit cold turkey for a week, that made me almost psychotic so now I'm back on it, and right now I feel INSANE I took 40 mg and wow talk about a tolerance break. I'm tweakinnn)
