Dear you,
Love yourself, because you deserve it. Love yourself, because after all you've been through, you should. Keep your hope in mind, and love in your heart. Accept your mistakes, don't dwell on them all hours of the night. Don't look too deeply into what people do, yes understand and delve, but don't find hidden meanings that aren't there. Let the relationships go that you need to let go. That means letting go of her, and being final. Be upfront, don't skirt around what you want to say, but don't be blunt. Take the confidence with your friends into other aspects of your life. Let the anxiety flow through you instead of dwelling on things you can't change.
