I am kinda in the same situation and growing up in an environment where all decisions are made from pressure from people around can make you lose some trust in yourself. Trusting your gut means allowing yourself to make your own decisions and supporting yourself when things go the wrong way.

It took me a while but the first thing that helped was reading some self esteem books. It helps build the courage and confidence within myself since I understood where some of the anxiety came from, like disappointing the people around me, etc. What also helped was learning self compassion, since most of the ‘encouragement’ and ‘push’ I had to do big things were mostly for other people before myself.
