How do I stop having issues with my work ethic?

Bit of background, I’m 20F. I have always struggled with being consistent and responsible when it comes to work; and the guilt eats away at me worse than anything.

I have diagnosed and medicated MDD and ADHD. While medication helps I’m still really struggling with correctly prioritizing tasks, not cracking under time constraints, staying late at work to get stuff wrapped up. I’ve noticed this cycle over the last 2-3 years, I get a nice job, I get overwhelmed over the work load when I struggle with a task, I start to spiral and find a new job when I don’t meet the requirements.

I’m now seeing a therapist over this, but I don’t want to take months and months to figure this out. So far she thinks it’s an “ emotional regulation issue”. Which could be the case I suppose,

I have so many goals that require me to have good discipline, show up for myself and prioritize correctly. ( I’ve been working out for the last 3 months successfully so far). I got a job that I love, but I feel like I’m failing due to the issues above.

Has anyone been in a similar spot and gotten out of this cycle? I just want to know some ways I can improve. I want to be so successful in life.
