There's no shame in asking for a small amount of help, The way your going now will lead to you burning yourself out and becoming agitated at the career. That or drive yourself mad trying to make it off your own back while at the very moment it may not be possible. I'm not saying ask your parents for a massive amount of money but anything will help, Its easy to pay them back if they can do it without putting themselves under pressure.
Best of luck in any case
