How to deal with gf becoming too lazy?

My gf has become increasingly and extremely lazy in the last few months, and I don’t know how to deal with that or how to approach communicating that with her!

When we started dating around a year ago, her baseline activity was not that high, but she did go to work, did her house chores, and we were going out 2-3 times a week, mostly bars, cafes and restaurants, nothing with much activity, and she also had the time and energy to go out with friends.

In the last few months, she has become too lazy to go out, we barely meet once a week/10 days, she doesn’t meet friends, she’s always procrastinating in her chores and barely does them while complaining. She just goes to work, get back home (we don’t live together), and is glued to her phone till she goes to sleep, just doom scrolling, binge watching AI slop! Meeting any weekday after work is days of negotiation, and most plans we make for the weekend goes to nothing after she wakes up really late in the day!

I understand she’s been stressed at work/home lately, but she’s just refusing to take any action, she just keeps spiraling down and I don’t know how to deal with that, and every day, it becomes harder and harder not to take it personally!
