I know how you feel... My adrenal fatigue worsened so much during this (and last) year that I had to quit my job, I am barely managing college and all exams, but thankfully I don't have to attend classes, I only have to take exams, which is a real struggle that is killing me and draining my remaining strenght.
Regarding coping with other people... They don't understand my problems, they think I'm lazy. I have problem within my family, because my parents are paying for everything (I can;t work and I have no money left) and my father is so terrible for me, he doesn't believe me, thinks I'm just lazy and that all is in my head. My problems started few years ago and they are tired with me and all my health issues. Sometimes I am really considering suicide, but I don't have enough courage. My friends? I have only two left. Other people just walked away. No wonder when ypu have no energy to go to parties, to cinema or anywhere with them (even talking is draining).
I don't know what should I do, because to cap it all off nothing works for me and I'm only getting worse over time, not better.
So answering your question: how to deal with people, I don't know, I just don't. But maybe someone else will give some advice...
PS. Sorry for my english, it is not my first language and today I'm in such a brain fog that it is even worse.
