I don't know what the trauma is, I could guess it's very bad. I'm sorry for what you've had to see, I'm sorry for the people suffering you see too. The risk imo is that it can send you into an episode when you've got bp (even non bp people too). So it's a good idea to catch it before it leads to something really bad, like things an episode can cause.
What are you into? Do you have a close friend you can unload and cry to process the trauma? (I don't have many real life people like this personally).
I don't have a therapist right now except mother nature. I went to the trees and cried. What's the point? I asked. She actually gave me an answer.
I went to the ocean and asked questions. She gave me answers.
I especially like to find an isolated psychic vortex type of location and connect, ask for healing, ask what to do with the heavy weights on my mind.
I go out to look at the moon and stars, I get filled up on mama love from the moon. It's very personal, but sometimes it's like she/ the moon is the only one who gets me & sees my pain.
I had a mindfulness therapist in the past who helped me get some really profound insight. It's not talk therapy, it was about tuning into my body & aura. It got too deep and I split from the sessions after a year. Thinking about going back again now though.
