Need advice asap- traineeship catch 22

[ilovechildren]

I was offered a traineeship role, but i am not sure whether to take it or not as they said if you quit in a certain amount of time, you have to pay them back for the training. Has anyone taken on a role like this, was it worth it or did they regret it. I hate feeling stuck, im someone who needs to feel comfortable and supported in a centre.
