Finding A Job That Works Around ADHD Challenges

I (24) have adhd inattentive type and so learning new things that my brain despite my wishes deems as uninteresting has been a challenge in school and now in the adult world which has made living incredibly difficult. Not to mention my inability to seemingly do things speedily even with medication. I have had issues finding jobs that pay well that work around my disorder and personal quirks.

I have been laid off for the first time, left a housekeeping job at a hotel due to not being able to keep up with the demands, and finally settled at a grocery store that isn't given me the hours I need all this year. I took on cross training in starbucks in hopes to get more hours. But today as I was struggling to remember everything and was taken aside where the manager expressed concerns over me not learning everything quick enough and she suggested that this may not be the job for me. This was something said to me at the housekeeping job albeit the starbucks manager was much nicer than the woman at the other job. She even is trying to find ways to help me process everything but I feel so hopeless.

I feel as though when I apply myself to almost everything and anything that I really want for myself I always fall short whether it is a personal or financial goal. What jobs have others with adhd done well at? How did you get past challenges? Any advice, insight, or even words of encouragement would be appreciated.
