Firefighter here. Diagnosed with ptsd, depression, anxiety, and compassion fatigue about a year and a half ago. I was managing as best as possible with therapy and hard work. I was very against medication for myself. I had suffered debilitating symptoms for 2+ years. It got to the point where I couldn't see anything but the darkness. I reached out to someone who does a lot of work with natural supplements. I started taking liquid magnesium supplements twice a day along with doses of tryptophan 4 times a day. I felt a weight lift off of my shoulders within hours. I have been on this regiment for 6 months. I still have some lows from time to time, but I genuinely am as close to my real self as I have been in years. It saved my life. There are alternatives out there.
