I feel you. I'm going through the same thing. I'm an introvert who recently became extrovert and I can't do 90% of the activities that made me an extrovert.

Here's how I'm coping:

1. Reactivated my introvert side with

   a) Reading more books

   b) Learning to play music

   c) Online singing lessons

   d) Exercising at home: i) Strength ii) Following through Supple Leopard (book)

2. Going outside once a day for a walk. No exceptions.

3. Chill at the emptiest park on the weekend.

4. Going on a hike during on some weekends.

5. Small talk and saying Hi to random people on the street.

6. Cleaning the house
