Hi Suzy,
Building up your self esteem is quite a complex thing. I am no therapist, but i too had/have a low self esteem on myself but it seems to get better by time.

Reading books about it is not bad at all, but its not the solution! applying what you learn is! Self esteem in my opinion is all a matter of thinking! What you think about yourself!

You should appreciate everything you do, even if somethimes it is not the right thing, appreciate that you try! Having a good relationship with yourself is what you should work on! If you are comfortable with yourself then there is no stopping you!

Therapists help, but there is no one way to fight your low self esteem, so do what you think helps you the most! if reading that book and applying it helps you feel better, then i think that is the right way for yourself.

The only thing is try to make it a long term thing, not just for a small time! Make sure you get to know yourself well because although this might seem to be the easyest thing it is not! For me it was one of the hardest things to do and i am still discovering things today that i did not know!

Have fun with it, take it as an adventure, a task which you need to do in life, once youve accomplished that you will be in peace with yourself and your self esteem would improve too!

I hope that i have explained myself well, if not just ask! We are all here to help you and there is no shame in asking for help.

Dont give up, it will get harder but its worth the trouble.
