I am pretty similar to this and would have described myself as having a low-grade depression that never lifted. I also have chronic anxiety that has gotten better with stimulant use, weirdly enough. I feel calmer and able to apply myself without panicking.

I started taking meds about 2 months ago and I was actually able to remember bills and my psych appointment. My psychiatrist actually got pissed off at me because I missed 6 months worth of appointments (avoided him for 3 months) and kept calling him a week after my appointment because of loss of time. I got lectured a few times about being responsible, whatever. I finally asked him about having ADHD and he told me that I have classic symptoms of someone whose inattentive and he suspected it.

But he still asks me how I graduated college. I had a lot of friends who helped, otherwise I would have dropped out. LOL.
