My friend borrowed 10k in August and I willingly gave it to him because he was in genuine need.

Now the year is about to end and he has not returned a penny. The thing is he always shows his intentions of returning the money but the time is passing. I never ask for it tho, what to say, Im kinda shy. Now it is not that Ill go bankrupt if i don't get the money but even I am recieving money from dad being a college student, so I'd need to get some money to suffice, moreover that being my own money. But yeah I need the money really very much rn. Please tell me anything that will help me
