Driving away after knocking someone's car

Q: I have a small problem. This morning I went to do some shopping. While parking, I misjudged my turning and by mistake I scraped into the car next to me. It was a very small scrape, maybe just a touch up would fix the problem on their car. Due to my financial situation I got scared and drove away without informing the person. However I am now feeling really really guilty about it and i fear Allah's punishment with regards to it, like I am scared Allah will take away barakah from my wealth that I have left or something else will happen. What can I do to fix this situation as I was scared to wait for the person to tell him what had happened.

Husband watching TV

Q: My husband watches TV a lot. I don't like the TV at all. I have some questions, is it fine if I tell him while he is watching TV or Youtube videos about something Islamic? Like for example I said today while he was watching a Youtube video, "today is the 10th of Muharaam we can buy food", or is it wrong and should I wait for when he is not in front of the TV or watching  Youtube videos? I thought that talking about Islamic things like that is wrong while he is watching haraam but I still did it. Also if I am in the kitchen and I can hear the music from the TV, and some sauces and spice bottles that stay in the kitchen have eyes on it and I am talkikng on the phone to a friend and I use words as "Insha Allah" and "make Dua" "Allah knows best" etc is that also wrong? I am doing that at the moment and I am feeling guilty please advise?
