Panic attack and boredem

Hey,
I’ve had this problem for years. It appears when I have days off.
For example, on the first day, I tidy the flat, do the laundry, and go shopping. Then all my tasks are done, and nothing is left.
I do sports, meet friends, or go out.
But in the end, I feel kind of unsatisfied because I haven’t done something productive. I didn’t learn anything new or meet new people.
Then I get panic attacks, become more easily overstimulated, because I can't find something that truly satisfies me or calm me.
When I have to write a paper for my studies, this problem doesn’t appear because I have something productive to do, and it challenges me. That satisfies my mind.
Can anyone relate?
