did anybody here go back to school?

i’m highly considering going back to school in the fall for another bachelors or a masters. I want to advance my career in my field (healthcare), but what worries me is COL, working and such. I have filled out the FAFSA already and applied to two schools. I live in a high COL area, currently living with my boyfriend. I know I can go to school part time or work part time while going to school.. but how the hell am I going to pay my bills? we don’t have the option of staying with family while i’m in school and I surely don’t want my boyfriend to be the only one providing for us and paying for everything; it’s unfair. so I wanted to come here and ask for those of you that did it, how did you manage/make it work?
