What's been your biggest mistake so far in life and what did you learn from it?

that i let my worries consume me and not sharing these too my loved ones. which then got worse and anxiety and depression set in going on for nearly a year, started to try numb the pain with alcohol and still did not want to be a burden. was the end of my relationship.
ive learnt that sharing your worries and asking for help are not weaknesses or burdens. numbing the pain makes it worse in the long run.
