I really regret that you sold your Bitcoin, even though within 1 year we will have a halving on Bitcoin, to be precise in Q1 or early Q2. If in the future you have Bitcoin again, and don't want to sell it but want to solve your financial problems at that time, we have a board for money lending in this forum [1]. You can guarantee your Bitcoin as collateral for lending there, on the one hand you can solve your problem, on the other hand you will not lose the value of your Bitcoin.
Most people will lend their money to get interest, this make the @OP need to pay the loan with the interest which is high. As you said above Bitcoin bull run might happen on the next year, no one will lend their money for a year since it's too long.
I don't think the @OP should regret to convert his Bitcoin to fiat for his family needs, family needs is more important than money. It seems like you're don't want to spend any money you get, it's better for you to stop eating to save more money to invest more Bitcoin.
