Before being up to working on trauma it's important to have enough coping skills to manage the extra stress. My supports have worked a lot in grounding (ie finding ways to keep yourself in the present - breathing, holding into a stone, feeling your feet on the floor, anything that keeps your mind in your body and in the present moment) and creating safety, whether it's a physical place or a place you imagine in your head. They've had me practice this often during no stress times, and then slowly increase the stress so that I can do it when I'm in flashback mode. It takes a lot of work sometimes, but it's something you could do without having to tackle the trauma. Just a thought, you could search both things online as well, there's tons of info out there on both.
