i was gonna say so many encouraging things to you but everyone before me already did . just hang in there, and change your angles. Lucid dreaming is something you need to figure out, not something you can press for. To me, its a hobby, and its certainly a sort of lifestyle as well. Confidence and attitude are two decisive things, but it doesnt quite work to demand a lucid dream, or to think that you deserve one for one reason or another. Neither do I think that lucid dreaming on its own will do something for you, like a sort of self-therapy. Its a great hobby to have but I dont think it helps with a stressful life like that. Go on and sort a few things out in your life first, thats how you get rid of some of the stress that you are having. Now, certainly you dont need me to break you some advice here like i m your pa, but I can see how stressed you are and its not necessary, nor is lucid dreaming gonna take that away.
