good for you - for making the decision. only you can say if it is the right thing for you - but it sounds like you have thought it through and carefully considered the alternatives. i can't help but think that this is a positive step - and a BIG one! of course - please keep us informed of whatever happens.
"Tell your heart that the fear of suffering is worse than the suffering itself... And that no heart has ever suffered when it goes in search of its dreams, because every second of the search is a second's encounter with God and with eternity." - Paulo Coelho
