I know you will always feel self-conscious, but you need to know that what others think about you doesn’t matter. You need to know when to move on from a negative comment. Never, ever think you are not good enough or that you have to change who you are to be liked by others. There will always be someone out there who will see the best in you no matter what. You have people in your life that love you and want you to be happy. You want to be able to live life to its fullest, but you can't do that if you are thinking about all those people who have hurt you. Sometimes the best thing to do is to move on, forgive, and forget.
I wish that you could see yourself the way that other people do. You think that others see you in a bad way, but they don't. You are the only one that sees yourself that way. You need to know that you are your worst enemy. You overthink everything, maybe you should think about the positive because that is what everybody is telling you to do, I think you should take their advice.
Always remember that being skinny will not make people like you more. How you act towards others will though. Being kind to other people will help everybody out. Even if you don't feel good one day that should not affect how you treat others. Having respect for yourself is also a big thing. Do not compare yourself to the people around you. The only thing that matters is how you think of yourself. So I'm going to tell you to always remember that you are loved more than you can imagine even when you feel like the whole world is against you, know that you have people who love you even when you feel lost and unappreciated.
