Anyone Re-Enlist After an RE-4? Need Advice

It's been over a year since I was discharged from the Army, and I’ve been struggling ever since. I received an RE-4 code, and it feels like I ruined my career over one mistake. I haven’t felt the same since, and getting back in has been on my mind constantly.

A Staff Sergeant who knows me is trying to help, and my old unit—where most of my buddies have now made Sergeant—wants to support me too. But since none of them have been in my position, they aren’t sure how to help.

I’m reaching out to see if anyone here has been in my shoes and successfully got back in. What were the steps you took? Who did you talk to? Is there anything I should be doing now to increase my chances?
