Hi,
I have had my share of awful confessions, similar to yours. My approach was to let time heal my fear of the confessional.
Others have already written it, but pray for the priest. He is also a mere mortal, heavens knows what was confessed to him that day, or what angered him. It is not okay for you to be treated that way, and you can always make a complaint to the Church where your confession was heard or ask to speak to the priest. Sometimes doing that can help you feel empowered.
I only say confession now in the city, in a church where they cannot see me and I usually only take two-three minutes. I do not ask for spiritual help.
If you are looking for spiritual guidance , I strongly recommend seeking out a spiritual director. They are an absolute blessing and they will have time for you—weekly, monthly, etc.
