I guess this is a would you reather question, if you were stuck in a position of living with someone so negative telling you that you have no chance of becoming a nurse, give up.
would you stay at home where there is free food and bored but negativity telling you, you will never make it and you will be lucky enough to work at mcdonalds or would you move out, work a job while going to school and support your self finacialy while being in a positive enviorment with no one waiting and hoping you fail?
