1st post- investigating adrenal fatigue

Hello, all. I've decided to join here after trying unsuccessfully to develop new friendships with others in my community. I'm sick of chasing after people who are too busy and already involved in their own lives. I'm seeking info from others who have experience with adrenal fatigue. What are the symptoms? What brings relief? Mainstream medicine is failing me and pushes mind altering drugs. I went through a hellacious withdrawal from Pristiq and refuse to risk that brain addiction again. Looking for safer, less damaging relief from my current near-debilitating anxiety. I don't want my first post to be too long, so that's all I'll say for now. Thank you to everyone who shares here. I pray for healing for us all.

I have tried sublingual B12 because I also am experiencing debilitating fatigue that makes me need to sleep in the daytime. It makes me jittery and I still need to sleep. I am trying 400 mg of Magnesium Citrate at dinner after reading about others' experiencing relief from anxiety. But now I'm confused about whether I need calcium with it for it to be effective. I'm stopping calcium today due to constipation. I'm cutting back on sugar and only one cup of coffee/day. Trying to eliminate white flour and most breads. I've read about cortisol levels and how timing of eating protein vs carbs effects proper levels. The more I read, the more I feel like I'm spiraling.
I try to take a walk everyday. I have Reiki every other week and psychotherapy every week.
I think I was born depressed, but managed to secure several professional licenses and run business throughout my 61 years on this earth. Only in the last couple of years, when I've had to care for each of my parents, a younger sister, and her husband until their deaths, have I found myself the victim of debilitating panic attacks that wake me from sleep and overwhelming depression.
about a year ago I stopped Pristiq---going through the most heinous withdrawal one could imagine. It took months to clear my system. I don't want to take any benzos ever again. So I'm looking at alternative medicine. Insurance doesn't cover, so the high cost itself can cause anxiety!
Thank you for listening. I welcome any feedback.
