So lately I've been in this really depressed mood...I get very defensive and I start fighting with my friends easily...I realized that I get really bitchy without really meaning it and I've been able to stop it however I haven't been able to get rid of this really bad mood...I also keep to myself when I'm in this bad mood and I'm not usually my perky cheery self and it bothers because I'm like an open book...Is this an ENFj trait?
