When I was a kid... I wanted a cabin in the mountains. I would imagine living there (forever), and being more or less away from society.
Fast forward... I own a house in a rural area and have a family. I'll likely never have that cabin in the mountains, and I'll never be free of having to support my family. That's my fault though..I took the path of least resistance and ended up where I'm at - I didn't take the path towards what I dreamed about having as a kid.
Well that's unfortunate. In this cabin dream, do you have a family or was your intention to live in a cabin in the mountains in isolation?
Regardless, perhaps make it a goal to do this when you retire. It will give you something to work toward and possibly quell some of your regret.
If it's on your mind this much, and I'm no expert here, you might want to talk about it with a professional. You can't let this stuff bottle up and eat away at you from the inside.
