Sorry to hear about your struggle.

I think you may have over complicated the matter in your mind, do not bother too much with the theoretical implications of Lucid dreaming at this point. Of course you can have a lucid dream, you have all the hardware needed already in your head.

Building new habits or neural pathways takes dedication, it comes down to simply practising some basic techniques over a period of time. If you are doing the methods you are making progress even if it not immediately obvious, changes must occur because every action has a reaction, especially in the brain.

On the point of using Lucid dreaming as a escape, this is reasonable but not ideal in my opinion. Lucid dreaming is best used as a general life enhancer, sadly one cannot just crawl into a hole in the ground and lucid dream ones life away, as desirable as this may be, one must still deal with the burden of a physical body. Reasonably Lucid dreaming will only take up a fraction of ones time, maybe 30 minutes or a few hours a day at best, then the question becomes how does one make the other 90% of ones life better. So yes lucid dreaming is a great escape from daily life, it is a wonderful way to spend ones time, but do not neglect those other factors of life or put all your eggs in one basket.
