Can we all take a step back and consider what acid is before we all jump on this bandwagon that OP was spiked with acid? Because as someone who knows what it is, this does not sound likely...at all.

OP says she drank "some" of a drink that was "spiked" with acid. LSD is measured in micrograms(ug). That is 1/1,000,000 of a gram. One hit could be around 20-150 ug. The amount of LSD it would take to spike a drink(that is to assume that it isn't broken down at all by the contents of the rest of the drink) to affect someone at all, let alone allow for OP to only drink "some" and feel effects is such a complete waste of valuable LSD that I can't fathom why anyone would do something like that ever.

OP:

1) your 20's is most commonly when mental illness begins to show itself.

2) LSD has not been found to make someone who otherwise wasn't predisposed to mental illness suddenly become mentally ill.

3) It is possible that maybe it was spiked with something else, but I've never heard of psychedelics being used in drinks outside of anti-drug propaganda...mainly because as I was getting at before, it's basically a waste of the drug.

4) Is it possible that it was the amount of caffeine + other things you consumed(alcohol?) that evening? I have had full blown anxiety attacks and depersonalization from just caffeine.
