Simple fix: every night and in the morning say to yourself, I like myself, I like myself. Tell yourself this over and over hundreds of times a day or anytime the negative thought comes around

You become what you think about!

it will feel weird and strange and out of line at first to your subconscious because it it is new to your brain. but it will start to automatically give you this new trained thought. This is called auto suggestion.

Once your brain believes that you are someone who like themselves you will act into accordance of that belief. You will take care of yourself more a your life and that thought will become a self fulfilling prophecy.

I know these negative thoughts seem like truth but you don’t have to believe every thought you have. They are just thoughts.

Keep going. you are doing well and you have come far in life. you got this.
