Depression (and many other illnesses, autoimmune, hormonal deficiencies, sleep disorders, all kinds of dementia and other neurological illnesses) will produce a dysexecutive syndrome that's very similar, if not indisginuishable, from ADHD.
In your specific case you may want to read up on something called "learned helplessness". Essentially you are being conditioned by failure to quit prematurely.
That is different from ADHD. ADHD in itself is really a diagnosis of exclusion, where no clear cause can be found.
In practice, ADHD is what you have when stimulants make you get better.
If your laundry lists of symptoms (depression, sleep disorders, lack of motivation etc) get better from stimulants, count yourself lucky. Stimulants work right away, if they work at all, and have few and relatively mild side-effects.
Some of the side-effects, like weight loss, are even seen as welcome by many people. Others like having to pee more often and cold hands are relatively easy to deal with.
For comparison, antidepressants take months to show even mild positive effects; and have major side-effects.

Funny how my conclusions today are the opposite. I didn't quit early enough somehow. Well it's hard to tell, tbh, I've spent years learning hard stuff without any real benefit. So many a different course of action would make sense :)
