It's obvious you will take a different route at sometime ,if being away from home is making you unhappy now ,it will only get worse ,but if you decide to pack it in ,it doesn't have to be now ,make the decision ,then make the preparation to pave the way ,give yourself six\twelve month to prepare financially ,to make contacts ,make yourself busy finding out all your options ,talk to your Mrs and your family ,if your properly prepared it will feel less like stepping off a high kerb ,
