Rough childhood, raised by bi-polar mom, how do I pick up the pieces of my shattered self esteem?

Wow that's rough, all I can say is stand up for yourself, believe in yourself, for who you are and what you can become, imagine what you would like to be doing 5, 10 years from now, work toward that, let your past go, forgive and forget, it won't help always regretting, let it go! You have so much to look forward to, so much to live for. Think about good and positive things, listen to calming music, there's even nature sound CDs they can help a lot, keep yourself busy and don't give up!!!
