Once I get started on it, be it cleaning or whatever, I finish it, but that might be the problem already.
Like, if I manage to get started on cleaning I'll spend the next 3h cleaning everything and completely exhaust myself which just makes it harder to get started on it.
I think the solution is to not try to "clean", but try to just clean one thing, like the shower and nothing more, then the next thing tomorrow etc.
Minimise the amount of preparation you need f.e. by making it easy to get ur utensils ready.
It can be really hard for me to do laundry because I need to go down in the basement, even though the actual work of washing is done by the machine and I spend maybe 5 minutes hanging the laundry.
If it's just a matter of getting started for you, then try this: Sit down with your head and back reasonably straight. Close your eyes. Take a few slow and careful deep breaths, and just relax and rest. From here, with your eyes closed, you will be free to notice and connect with the fact that you want to get this done. It's not really a conflict for you, because you already know it's what you truly want. That'll be extra clear once you get it done. And the moment you connect with that idea, just stand up and slowly start doing whatever you feel comfortable doing.
I wish that would work,..
For me it's not just cleaning or similar chores but every thing I need to *do*.
Yes, even things like getting ready for bed, for some reason they're extremely stressful for me, more than just exhausting, it's more like mental pain.
And because of that I get scared of those things, even something like going to sleep or getting up gets me scared.
I've tried relaxing before such things but because of that I'm unable to relax.
For example when getting up in the morning, it's actually pretty interesting.
When I try to get up I'm so scared that I can't, but as soon as I accept that it won't work and give up on it, deciding to rest some more, suddenly the stress and fear vanishes and I'm able to relax.
