Hi Crashy,
I'm sorry to hear about your bad experience regarding LD, and WILD in general.
Well all I can say is you have acheived more than me in that department, so good on you for at least trying and giving it a go.
However I'm like the other Guys on here that don't want to see you give up as such. The only thing is at the end of the day you are still young (unlike me?) and you can come back to it whenever you feel like it.
Take a break if you must, or relax a bit. Enjoy your life. Learn to drive. See your favourite bands, etc.

I have been there when I was at Art college. I bought 'the book,' the 'T shirt,' etc. if you know what I mean about LD and OBE when it was less known about. (There were no websites back then.)
Sure enough, I ended up with the 'old hag,' the bad FA's, the hallucinations in the dark, and the strange turning and twisting sensations which made me sh*t bricks.
I told some friends about hypnagogia and the voices you can hear, etc. and they looked at me like I was mad!
Then, like you, I was young and impressionable at the time.

I had a break from it, but I still always had a basic interest in dreaming, etc.
I returned when I felt that I was more ready, knew a little more, and where I could devote time, as and when I could choose, without outside worry or anxiety which could influence my experiences.

I would have thought (as some of the above posters have mentioned) that DILD would probably be the best option for now, but at the end of the day it is your choice.

Regards and good luck.
