Struggling with unmediated ADHD

The last couple of months have been a nightmare for me in terms of my ADHD.

I was diagnosed about a year ago and haven’t really taken medication for it. For a long time, I was just used to things being chaotic and I was working a job that I could do with my eyes closed so it didn’t affect it too badly. I ended up leaving that job due to the mental toll of taking a promotion that was not the right fit for me and now I’m without a job (I have one in the process but still).

I feel like I have no grip on reality, I dissociate every once in awhile, I am constantly overstimulated, and my diet/sleep habits have suffered. I am not sure how to proceed with getting this taken care of and honestly am scared of trying medication.

Any advice welcome honestly.
