Paying back money owed to people

Q: I'm going to be as precise as possible. We are all humans, but I'm a Muslim too. From childhood I may have taken/borrowed someone's money and never returned it back. Like I ask Mom to give me 100 I'll pay u back, but I don't, or I go to a store and the bill is 12 rupees and I pay 10, I say I'll pay u 2 more next time but then I don't coz I literally forget. I mean I even stole money from my mom n dad a few times, it caused fights but I never got caught. But now as I know that I'm mature enough and I repent what I did intentionally or unintentionally I want to pay back every single person I stole money from or borrowed it or just forgot to pay back. The problem is I have 0 to no clue that how much money I actually owe and to whom. Please help me. I give donations and stuff in the name of Allah but I still fear I might still owe people. I'm fully aware that my sharing this question with you is making you a witness of my sins but please don't judge, I'm only trying to seek help and Allah's Forgiveness. What should I do?

Revoking a talaaq

Q: I have said to my wife on telephone call "that I divorce you". This is the first time I said this.

1: Can I take back my divorce without intercourse as she is in a different country and we cant meet now? So can I take back verbally only?

2: My wife is a doctor, so during iddat can she work as a Doctor in her country?

3: Me and wife live in seperate countries so can she do her iddat in her own country or is it necessary that she lives with me during iddat?
