in doing what you did you snatched back a huge chunk of the pieces which Rachel had pulled off you over the years, now take time to stick them back on to you, you need to be kind to yourself for the glue to work, tell yourself every day you are a great person, you are a strong person you can assert yourself and it is ok to.
you have to start believing in the great strong you, you fought the bullies and won, that is something to be proud of and a reason to hold your head up high. so stand up tall, puff out your chest, chin up and get out there girl,don't look back, look forward, make new friends and don't stand for any crap ever again!
