Should I quit this trade? (Canada)

I'm a slow learner. I have undiagnosed ADHD and major depression. It took me almost 10 years to finish my apprenticeship. It took me 6 hours to finish my journeyman exam because I had to request special accomodation.

I started a job last month at a mine up north. Received a call today that they were doing workplace adjustments and that I'm being laid off. I think it's my performance as a Journeyman. I didn't have a very good apprenticeship and had no one to teach me how to he fast and efficient. Honestly I'm thinking about giving up altogether because I'm licensed but no one wants to hire someone who's slow and inexperienced.

I've been bouncing between electrical and non-electrical jobs for years because the industry in my area sucks.

Maybe I'm not cut out for this even though I enjoy it.
