It is clear that opportunity to get some education is very important for you my friend. I think everyone, including the people enjoying your delegation would totally understand if you powered down to cover possibly life changing expenses.
An option that could help you, is to ask for a loan here in this community.
I know 2 users that can help with this.
@neoxian and @decentrabank .
I really hope you can get the education you deserve.
Cheers mate.
