For anyone else struggling with this, what helped me the most was sprinkling motivational/uplifting music into my music playlist. It's a constant reminder to work on my mental health and helps with the consistency aspect thats so hard to keep up with otherwise. Fearless Motivation makes some good motivational songs.
I loved for Pingu when I was a kid, was one of the only shows I refused to miss. I'm pretty sure my inability to react in a normal way is due to me obsessing over him.
I decided to take up embroidery recently because I heard needle work was really good for people with suicidal ideation and ruminations. It's something that reliably puts me in my happy place.
