I think you're obsessing about it a bit and you are possibly burning out. I was in a similar situation a few months ago, where I was reading books, researching, thinking about LD and doing RC all day long, yet nothing happened.
I was trying several different techniques each night and that was affecting the quality of my sleep.

We need to remember that it takes time for the brain to learn new skills. You wouldn't read a book once and expect to remember the majority of the words in it. You wouldn't go for a 20 minute jog and then expect to run a marathon.

Honestly, the best thing I did for my LD was to stop trying for a while. All I did was to tell myself I would have a great LD every night before going to bed - and nothing else. I had no LD for quite a while, but it gave me time to think and see where I was going wrong. It gave me time to rekindle my desire to LD. Then I randomly had a DILD and since then I have started working towards LD again, but this time I have a different approach.

I am more selective in regards to what technique I want to try - and I will stick with one technique for a long time. I try not to stress about it if I don't have a LD, because I accept that it is perfectly normal - although highly frustrating - not to have LD every night of the week.

In regards to meditation - I practice mindfulness and this has helped me to be more present in the moment in my everyday life. But also, when I do become lucid now, I don't rush anymore, I don't get overwhelmed by excitement and I am able to keep calm and keep the dream going.

Hope you find my advice useful - keep reading this forum, it's a gold mine for LD!
