You don't say if you have a feel for whether this new job will have the same level of stress and negative factors (bad boss, lack of training, etc) as the prior one did so maybe making a decision like this is premature. It might turn out that this job will be better than the previous one but you won't know until you give it some time and an open mind.

Keeping your eye on your goal, saving money to get a job abroad, will help when things get rough.
