as nauseous as it makes me feel saying these next words...
would applying for Ryanair not be an option for you? I don't know if their recruitment policy of 'get 'em young, get their blood and/or money' would help you out not being a cadet but it may be worth a punt may it not? Not a perfect job but all the guys I know there earn good money and have a predictable roster, even if they do have to spend some of their time away from home...
sorry for mentioning the 'R' word, I am currently filling a bowl of soapy water for my mouth...even though I typed it rather that saying it, I feel a little self harm is warranted anyway
good luck anyway, never nice to hear a story like yours - all the best for whatever decision you take!
