Discharged From Marines Under Administrative Separation For Misconduct.

Hi all,

So I'm not sure if the flair is correct, but I was discharged from the Marines over a year ago for misconduct, commission of a serious offense. I received General, Under Other Than Honorable conditions discharge, and I'm curious what avenues I can go down to upgrade it if possible. I couldn't find a military law subreddit to ask on.

Little bit of background: I was initially going to be discharged for mental health, my ex wife was emotionally and physically abusive towards me and ensured I couldn't deploy my entire enlistment. I ended up going to mental health where I admitted to suicidal thoughts. I also have been diagnosed with ADHD, and I more than likely have Autism Spectrum Disorder. Towards the end of my enlistment, my ex wife filed for divorce and accused me of domestic abuse and sexual abuse. NCIS investigated me for about a year, but they found no evidence of wrongdoing, and it was a he-said-she-said situation (I saw the investigation documents and it was one page of statements and nothing else.) I was a shit Marine due to mental health struggles, and at my admin board they tacked on the domestic abuse charges. Because it was an admin board, they required a "preponderance of evidence", which is as I understand, the board being 50% sure that I could have committed it. The board also had several members who I knew from my old chain of command, but prior to this our unit was split apart into several smaller ones. I was not convicted or charged with anything, but I was discharged with an other than honorable characterization of service. Do I have any options at all at this point?

Thank you to anyone who responds.
