If money should become an issue, you could always earn a bit on the side as a freelancer on platforms like upwork. In any case, I think this decision of yours was a good one. You will definitely get some answers and will become a little wiser in the process. Moreover, I get the impression that this was a decision made by your heart and courage even though your brain made you aware of all the consequences and possible "dangers". I'm rooting for you and I am sure you will succeed in some way. Even if the app shouldn't bring in a lot of money, you will gain a lot of experience and tools for future endeavours!
