I hope Nick finds this because I have little faith that the comment I left on his 2nd YT video will be found amongst the 1000's of comments.

In Anchorage, AK we have the Chris Kyle Patriot Hospital for mental health. It was established by veterans for veterans. I realize you're on the complete opposite side of the US, however, the option to come for treatment may still be available. A change of scenery by visiting Alaska may really help you heal. There's also research being conducted through MAPS on MDMA, Psychedelic and ketamin assisted therapy for war vets. Here's a link to learn more about MAPS https://maps.org/mdma/
I sincerely hope Nick reads this and learns about the additional resources available for his recovery and wellness.
Thank you for sharing your story. War vets sharing stories like this that I've seen publicized over the years to bring awareness, have primarily focused on Army vets in my opinion.
Marines are first in last out. Of all the branches, the Marines are trained the hardest. One does not simply join the Marines and magically you get that title. NOPE, you are a recruit until you finish bootcamp. 13 weeks of hell and if you make it to graduation day, then and only then will you EARN that title. The training is no joke. You are a killing machine. Unless you choke and like Nick stated, there's always a need for cooks. I'll wrap this up for now with this: Nick your bravery on the battlefield in real life and on the unforgiving platform of the internet is steadfast and inspiring. May you find respect, admiration and encouragement from these words. I wish you the best on your recovery journey.
