Tasks that involve your hands are very good. Tactile stimulation with casual thought about the activity is good. Playing Solitaire with cards.

I think it is important to find things that occupy your mind so you do not spend time thinking about life.

I do not have a problem watching TV. But, I need to wear earphones so I can process the dialogue without having to sort out the ambient room sounds and echos. Same goes for computer time. I watch YouTubes of documentary and informative programs. History, industry, etc.

If I start to struggle to focus on what I am watching, I will change to a different activity.

I will overload trying to read a book within a few pages or sometimes, a few paragraphs.

So, try to find things to keep your hands busy. Learn to knit, crochet, Swedish weaving, etc. They are very therapeutic activities. My wife teaches Swedish weaving to school kids. They love it and some even said it helps them settle down.

Adult coloring books are very common now. Build models.
