I agree a 100% with everything martin777 wrote !
I feel for you, but hope you will find some things that will make you feel better.
Adhering to a routine is hard, but if some things motivate you enough, you could manage it (after some time) !
My first pièce of advice would be to go easy on you when you stop doing regularly some activity or other : I have kind of accepted that my interests are on a rotation. I have a (mostly fixed) number of things I like to do, but when my schedule changes a bit, or fatigue and anxiety take too much of my energy, I know I will have to focus on « just » staying afloat ; and then, I know I will abandon my current interest to focus on daily life, then get better, and be able to start a new routine with another activity, and so on. But I know I always come back to my « core »activities - each on their own time !
My prefered activities are :
- learning Italian on Duolingo
- learning chess with the Chess app
- drawing
- watercolor
- reading +++
- jigsaw puzzles 🧩 (I’m not sure I have the name right, but emojis are very handy so you see what I mean 😅)
What helps me stick with activities :
- the streak, like martin777 said ! So apps are very useful if you can afford them…
- doing things with people : I have a book club, and even though it doesn’t guarantee I will read the book, it helps me stay committed to the activity, and it gives me a great safe space with like-minded people.
To be able to « start », maybe you should also listen to what you FEEL LIKE doing the most right now, and not what you SHOULD do right now : if you feel like exploring Spanish on Duolingo instead of working out, eventhough you haven’t been doing your work out for 3 days in a row, well I say go for Spanish ! It will all work itself out in the end : but because of task avoidance, you’ll probably be better off if you stop tormenting yourself with « shoulds » and « musts »…
Good luck with your hobbies !
