Human Factors; Procedure
I decided to do some practice approaches with my safety pilot. I got gas at ZZZ1 and it was a direct line from there for the approach into ZZZ so I did that one first. I got the weather; which was favoring the opposite direction; and changed to the advisory frequency. Another airplane announced that it was on the the approach for Runway XX but was farther out than we were. I announced that I was on the approach for Runway XY and would break off early. There was a lot of chatter on the radio both at ZZZ and at other airports that shared that frequency. We heard someone else mention Runway XX but couldn't make out what they were doing. I broke off the approach at about 800 ft. and 2 miles from the end of the runway as I knew I'd be far from the aircraft on the opposite approach. That's when my safety pilot saw the near miss plane that had departed Runway XX at some point. We never heard them announce taking off or on upwind and they did not show up on ADS-B (Automatic Dependent Surveillance-Broadcast). We immediately turned left for the missed but were past them by that point. After we passed them and announced the missed; the pilot of the other aircraft said something on the radio that I couldn't make out.Contributing factors were me continuing an approach in the wrong direction longer than I should have given the heavy chatter on the radio. The other aircraft was also not announcing enough or not announcing correctly or getting stepped on by other chatter or otherwise unintelligible. Another contributing factor was the other aircraft not having ADS-B Out installed. It wasn't required there but it would have greatly helped avoid the near miss. Given that we did hear another mention of Runway XX; I should have asked for their position since I didn't hear it the first time. In the future; I will break off opposite direction approaches much sooner when there is other traffic in the vicinity.
A pilot on final approach to a non towered airport reported a near miss with an aircraft departing the opposite direction runway.
