Amira I feel that it's more complicated to have breaks because this gives a bit of a feeling of becoming a lot of focused on the free days and I am not sure if I want that focus.
I'm not sure if this is your only issue with releases, because you also described unwanted feelings once you were locked up again, but if this is the major issue with you having breaks, why not leave it up to your mother to decide when you get breaks, and not tell you? Then you can't anticipate on them, but still occasionally enjoy free time.
(Of course your mother should use different durations between the breaks, so that you can't learn when to expect one.)
