Definitely sounds like a stress reaction. The worst thing is that you can become conditioned negatively this way as you mentioned getting it just when reading set-ups. How's your trading results in this state? Are you making money? If so - feel free to proceed. But if you're getting the shits and losing money on top of that - please leverage down.
During the same day, we got a guy claiming himself to be Mark Cuban, and another guy starting a thread about shiting himself. (maybe even the same troll) Must be a moon cycles. Damn, and some are giving serious answers. Both on ignore. p.s look at the sequence of the thread names : (the lowers one is the first one)
I suggest just dumping a load in your pants. The disgusting result will either cure you or you may find that you enjoy it, in which case seek professional help.
