Same thing happened to me about 3 days ago. The worst part is it was a complete set-up, pretty much the only people I considered friends got me to leave the house at a specific time so that they could let somebody they know when to break into my home and steal my grow. They got a bunch of weeks early plants full of ferts, that I had just watered, and even stole my hps. Left me with a broken front door and a room full of dirt. Goddamn I'm crushed but I can't really do anything except stop associating with them altogether.
I pretty much have quit society at this point. The last ppl in the world I actually talked to just totally betrayed me and the only way they were able to do is is by abusing somebody who's completely alone in life by taking advantage of their good nature. It's shameful. I really don't see how society can perpetuate itself like this, and I actually thing that it won't be able to indefinitely, eventually greed and selfishness will show themselves to not be admirable qualities but actually possessions of weak and feeble characters, but I think it's already too late and the damage has been done for me, at least.
