Here's an amazing practice to increase your self esteem:
Every day, focus on your wins and neglect your losses.
That's the main "secret".
Reflect on all the things you did well today. Focus on them. Embrace them.
Do it every day.
That's how you rewire your brain correctly.
Heal the parts of you that still grieve being forced to grow up too fast so you can slowly birth the version of yourself that you were always meant to be.
