Past issues seeking clearance (trigger warning)

I have four things that I fear may cause a hiccup and I was wanting to evaluate my chances before I pursue an internship at the cost of other opportunities, and get rejected.

  1. Two histories of self harm. Once when I was in middle school and a second time as an adult.

  2. ELS discharge from the army. I received a non - characterized discharge from the army resultant from the incident above.

  3. Drugs. fresh out of the military I smoked weed once (I know everybody says it was just once but this was legit the only time.) and I got a hospitalization like a month after I left the army for my Alcohol Blood Content, which I drank while I took an extra drink of my prescribed cough medicine.

  4. Debt. I have like 700 dollars of unresolved medical debt that I don’t want to resolve due to it being from a predatory insurance practice.

I really want this job, how bad do these hurt my chances? All of these instances were from like 4 years ago, I’m now doing much better, and have had no issues since.
