Trauma and Sadnesss

So I was going about living my life as normal, and then in a session with a coach, we discovered that I was having a trauma response/reaction to a circumstance. And I’m going to start therapy in a few weeks to process what came up. But it feels like since I’ve just been a mess. I cry all the time and life feels really hard. It almost feels too big to coach myself out of, it’s like I’ve just opened the doors to this ocean of sadness and grief and anger. And I don’t know what to do with it. I try to process it but I can’t feel it in my body like normal. It’s making real life impossibly miserable. What do I do?
