How do you de-stress?

My MIL has been stressing me the hell out and I know my daughter can feel it, shes usually kicking me all day and these past two days (the days I’ve been stressed out) I’ve barely felt her. How do you clear your mind and try to de-stress? I’ve tried meditating and I just can’t seem to shut my mind off for that to work. Usually I’d shop but I don’t wanna spend money 😂

I’m trying not to even think about my MIL but she’s just so disrespectful it’s hard to put it out of my mind.
