Qamar, you've got a lot to deal with at the moment - that long drive to Scotland and leaving your daughter there, and of course your diagnosis. This must be colouring your feeling about life in general, so even your LS doesn't bring you pleasure like it usually does. I think Malc's right: the issue isn't your car, it's everything else that's going on. When we get low, even slightly, we can find it difficult to take pleasure in anything. I think the medical term for this is anhedonia. And I'm not surprised you're feeling low. The good thing is that you've admitted it - to yourself and to us. You're not broken, you only feel broken. I wish you well. Send me a private message if you want to. Happy to chat off here if you need to unload. All the best.
Andrew
