What type of discharge would you get for mental health issues (suicide, depression etc)? What impacts would it have afterward?

Yesterday you posted about just arriving for AIT. If you are having issues, get the help that you need.

Don't worry about a discharge, worry about your mental health. Go talk to a professional asap. They are there for YOU.

Too many unknown factors to give a good solid answer. What I can do is speak from experience in regards to a former Soldier of mine went before an MEB with all kinds of doctors and Officers for his hearing for a possible Psych Eval discharge. He wanted to stay, but everyone else said he had to go. For his safety and everyone else's. He was recommended for, and received, an Honorable. The worst discharge level I have seen for Psych is General Under Honorable Conditions.
