Hi Op
Interesting Ted Talks Youtube ect would help you with techniques to improve your cofindence, and in social interaction too.
Don't give up doing Arts and creative writing that you enjoy and boosts your cofindence,
Don't worry what other people think,
They wouldn't try and change themselves to please, you,
They would only do this if they wanted to,
I think you need to be adventurous and explore hobbies (interests that you are curious about ,
Only take part in activities like this,to please yourself, !
Don't do these for other people's validation, (to please other people).
Don't worry what other people think, either ,
Nobody is perfect,
what makes us Speacial as individuals, is our uniqueness , is our quirkiness, qualities,
It be be boring if everyone was the same in life, !
Take part in hobbies (and interests that you enjoy purely to please yourself that's essential important in life
Be your own best friend,
Eventbrite is a good website for Arts 🎨 stuff aswell as stuff not related to Art subject
Youtube Internet is a good website too
Also look at improving your personal well being by taking mediation and yoga or chair yoga and other interests such as joining healthspa doing swimming 🏊♀️ sauna steam jacuzzi if its your sort of thing ?
Also Holistic Therapies treatments can give you a boost of feeling better too,
Will boost your cofindence, make yourself feel better,
Also spend time in nature,
Do spiritual stuff,
(Doesn't have to be Religious stuff going to church .
Also I sense doing volunteering work stuff activities for e.g nature conservation,
anything you are curious about and potential will enjoy,
Will be seriously beneficial for you in lots of various ways,
Plus you will have fun and potentially make new friends too,
Be surrounded by like minded people,
Also bonus too, it will improve your cv, if you later down the line want to do something financially better in life workwise,
Watch things on TV or on Internet read books magazines ect
Anything that will you feel better about you feel better positive about the world,
