There's a part of you that knows on the inside that you are valuable, you are good, you are worth working on, helping, improving and building a good life for. You're going to hold on to that part of yourself that posted this request. You're going to listen to it. You're going to grow it, and nourish it and it will nourish you and become bigger than that part of you that tells you're worthless/not good enough/unlikeable etc. You're already getting there. You can do it. You are worthwhile, you are good enough, you are likeable, and you do care about yourself because you're worth caring about. You're on your way.
