How to stop doubting myself
How I did it: The very first thing i did was learn about my identity, as in: what was it about myself i doubted? why do i feel i can't achieve anything? Obviously you can't just randomly know these answers, so make sure you're close to all the most important people in your life so then they can help you get on your feet. I chose my best friend.
The first thing i did was ask what it was they liked about me. I wanted to know why my best friend wanted to be my friend in the first place.
Even if i didn't agree with what they said about me, i wrote it down on post-it notes and stuck them 2 my everyday places (eg - mirror, bedroom wall...) and whenever I felt i was ugly, or fat, or i didnt deserve the air i breathed, no matter where i looked i saw the post-it notes to remind me that i had things other people liked about me which covered my 'flaws' (:
Sometimes it was hard so i read it out loud several times over, and soon enough I had memorised them :D so even if someone at school called me something, all i had to do was remember it wasn't THEM that mattered, but the people that cared about me that did ^^x
Lessons & tips: Never listen to people that want to knock you down. They only want to knock you down because they can notice you believing in yourself, which means they have more of a chance of their flaws being noticed.
Yeah the post-it note idea sounds kinda lame, but at the end of the day it works and its worth it, even if it means your bedroom walls look like their covered in a collage :L
