I know what you mean.  I feel like an old soul too.  There's just so much immaturity around me sometimes, and I just feel like that's far behind me.  Maybe being an old soul has something to do with the fact I either love something or hate something; I have a strong opinion either way.  

Also, to acknowledge another poster - I, too, have felt uncomfortable around groups of people, too.  Just stick it out and enjoy it anyways, otherwise you'll hibernate.  If you are a Pisces, this might explain it too as Pisceans tend to 'not want to go out' after age 25.

I've been having a hard time finding crystals with vibrations that are 11. Anyone know of any besides garnet and jade?
