Been there! Know exactly what you are talking about. Once I identified the problem I could observe it without judging it. The healing began. Don't be harsh on yourself, when you feel it remind yourself that you are in the process of healing and you will get better.

Maybe focus your mind on something that isnt yourself.. Imo ovely low self esteem is like reverse narcism .. I think its best to just not even think of yourself much less worry about other people's opinion of you. You aren't inferior to other people.. So they shouldn't think you are. Or they're wrong.. So dont worry about them :) and dont think other people are better than you.. :)

Its a good thing knowing that you have issues with self esteem. Lots of people have no idea why they feel the way they do and believe its because they are infact worthless.
Knowing you have low self esteem you know its not really your fault

Take it one day at a time. Work on yourself physically, mentally and spiritually. It's a tough but wonderful process to become more confident.

Be confident in who you are right now.. there's nothing wrong with you as you are.

Just say what you really want to say. Just be your honest self.
