Help please? Going to college?

So I’ve been reallyyyy wanting to go to college. I’m just nervous and confused on when to start because to succeed as an LPN, 12 months isn’t bad then next me and my fiancé will be able to build a house together next year. The only thing is, we are very tight on money currently he works at lazyboy. Makes pretty good money, but work is running slow right now again until usually summer and winter they run good. I want to go to college but I also right now want to help him out the best I can with just a couple bills. Nothing extreme but right now we’re living pay check to pay check living with my parents, we pay 100 a week. I want to get a part time job but I don’t know if I can handle it. I know it sounds dumb, my sister has really doubted me handling a part time job and going for lpn, (she’s an lpn) moving forward to something else I just feel so stressed I just want to go to school, graduate, do what I enjoy in the work field and make decent money so me and my fiancé wouldnt have to worry as much with ( combined income) can anyone help what I should do?
