Teething anxiety

Last night my son had the worst night we’ve had in his 6 months of life because of (what I assume is) teething. He’s usually a very happy and chill baby so he doesn’t cry hysterically at all really, but last night he was screaming and crying in pain for hours and would not let us lay him down. I went and bought all the teething things today but please tell me it gets better quickly.

My heart absolutely broke seeing him in so much pain and now I’m feeling like an anxious mess because I’m so worried we are going to do it all over again tonight. I have PPA and I didn’t think this would be something that would set it off but hearing him cry the way he was has triggered it.
