True. I think confession can be beneficial not only for mortal or venial sins but also in reflection.
That said, just as there are priests who give better homilies, there are probably certain priests who give better confessions. In my opinion, a good confessor is someone who matches the need of spiritual guidance with the need for spiritual truth. Sometimes I feel some priests are one extreme or the other. Too much spiritual truth can scare away a novice while too much spiritual guidance can ensure that someone stays in a state of sin that is dangerous for their soul. Absolving someone of their sins is one part of confession; the other is spiritual direction where the individual seeks help from the Holy Spirit for true repentance is the other.
I think this is a venial sin, but as otjm said, go to your confessor for some spiritual guidance hopefully.
