Ive also read about and experienced myself this type of anxiety from test. One thing that I figured helped Alottt was abstinence. Alot of ppl disagree that abstinence raises test levels but since ur on cycle ur controlling ur test levels but there's also something else going on in regards to abstinence its the dopamine/ prolactin Ratio. Excessive ejaculation depletes dopamine and spikes prolactin significantly that increase in prolactin takes days, sometimes week to drop to normal as ur dopamine levels rise to normal. Some might disagree with this but from my personal experience abstinence both on cycle and not helped tremendously with anxiety..
