Starting new chapter in life

Two weeks ago - I was offered an opportunity with the gov't and have decided to accept this position. This will be the start of a brand new chapter. I've been with the same company for over 15 years - for better or worst - it has become the security blanket I cling to when things in my life goes wrong. To finally let go of this security blanket will be an experience that terrifies me - but one has to grow....I hope this opportunity will allow me to let go of all the same old same old and actually take a step into the water instead of treading the waters of life as I have done since as far back as I can remember.
