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.
We are often troubled, but not crushed;
sometimes in doubt, but never in despair;
there are many enemies, but we are never without a friend;
and though badly hurt at times, we are not destroyed.
- Paul, II Cor 4:8-9
