My tip would be to really get in touch with you, and love you.
I journal everyday, write, draw, collages.
Two dogs are my constant friends and companions who model unconditional love, loyalty, and are great listeners.
Read, learn, be inspired by nature, outdoors.
These are my personal things, and of course day to day life and living is the best teacher.
Simple stuff, just mold your interests, try it out see if it clicks for you.

Sorry that relationships are challenging. I am an introvert too, and it is sometimes overwhelming.
Please know this is a wonderful loving a safe place here and lots of care surrounds you.
sincerely
Jade
