Firstly this happens to so many people. Going hard, recognising the problems that can go hand in hand & trying to balance this with the rest of their life. Forgive my ramble as follows....
Some can do it. Some don't care. Some just grow out of it, leaving it all behind. Some say its all about the music..when its all about getting loaded. There are always two sides to the coin, so don't spend to much time thinking mega deep, that might be the worst idea, and just leave you spinning in circles with a bunch of unanswered questions.
For example many say never will I do this or that again....then only to go on and do it every weekend for say the next 5 years. That does not make it bad. It is just personal choice. If it turns out wrong and shit, well then do something about it. And don't forget to laugh, especially at yourself.
Your ability to recognise that what your doing is/might be escapism is an example of good clear, rational thinking. But hey we all need some escapism. If parting takes too much of a toll, find other ways to get your highs out of your life.
BUT Don't beat yourself over and over with guilt. There is nothing wrong IMO, with looking forward to something and enjoying some hedonism...and hey doing it less might mean that you enjoy it more, and never loose the magic. So if you decide that less is more then all good! Or if your current choice is driving you nuts, well shake it up. A Different job or work with a means to an end like travel would be a great idea.
It's a journey time we tell and its different for everyone, but it sounds like your considering what else you want out of life and working towards that. So maybe ask yourself what you want, and work at that, rather than focusing on "if you have a problem". And thus Edith my ramble.
