Glad what I said resonated with you.
Here's a suggestion for dealing with the 'loss of intention'.
You had unused gym equipment and wanted to nurture yourself cooking things (that were healthy as well as tasty?). And you wanted to listen to audio books.
A £20 Puregym membership gives you a place and equipment for no more than £5 weekly, just a bit over a pound a visit, where you can have time for yourself. You have access to rowing machines, treadmills, ellipticals, weights, cycles at any time, where you can go there, put your earbuds in and listen to those audiobooks whilst you do something that actively does something good for your health, both physical and emotional. You're not looking at other abandoned projects, tripping over stuff or having to lift three washloads of clothes off the machines to use them. You can just stay there and zone out of the everyday things you were actively trying to distract yourself from with your planning and searching and shopping.
All you need to go there is a comfortable pair of leggings/trackies, a sports bra, top, cheapy trainers (as you don't need expensive ones for rowing, cycling or weights), water bottle, padlock, phone, earbuds, keys. So you're travelling light, you don't need to buy hundreds of expensive things and find space for stuff in your home.
You've now made time to care for yourself, you've had time to listen to your latest book, you've done something that will make you feel less twitchy, satisfied your head's 'RUN AWAY!' instinct that was misfiring into 'freeze in one place, barricade the doors with stuff' by doing something your body and head thinks was 'well, you ran away, the threat's gone, time to relax now' and you'll start feeling the good effects of being stronger/fitter very quickly. And it's outside. You'll get fresh air, sight of something other than the four walls and Stuff (or absence of Stuff), daylight and time without anybody demanding anything of you whatsoever.
This means you've decluttered your head of a whole load of things, your phone of an unlistened to audiobook, a restless body, and the feeling that you need to do something to fill a space you can't quite identify inside you.
And when you come home, you're not as likely to be craving baking cakes or fancy things, you'll be wanting to have things that taste fresh and light and nourishing. So the unnecessary kitchen equipment is gone. You didn't need it. You're hungry and don't need anything beyond something nice to eat, rather than having to find some space, wash things up, find the bits and pieces in the back of cupboards, go through complicated processes, give up halfway through and eat any old thing, then dump the cluttery bits all over the kitchen, thus making it less likely you'll want to spend any time in there next meal.
Most of all, it's giving you an escape that is utterly for you and your benefit.
Could it be worth a try?
