i seriously doubt you are 21
how can your family be able to control you when you are 21
you are mature enough to make your own decision
i live aboard by myself when i was 13 without parents and relatives
i can still survive by myself
being constrainted by family is not an excuse
you only have two choice
no. one: find a job heal the turtle before you buy another one
no. two: let go your turtles and let us adopt them
don't be silly and nonsense
eventually no one will offer you any help
