I appreciate everyone's posts, and I will look into the bipolar disorder. I'm pretty sure I'm not bipolar sober, but I won't rule it out.

BAM problem solved.
Except - it's not that easy to simply look at bud and tell if it is indica or sativa. The difference between the two strains may appear insignificant to you, but to people with anxiety it's of huge importance.

Furthermore, I was trying to stimulate conversation and possibly find a sound reasoning for why this happens with sativas only. I don't know of any reason why sativas and indicas should have such different pharmacological actions [on some people] despite being so similar. Maybe someone does.
