What should I do?

I got laid off in Jan. Took 4 months to land a job finally and joined a new company in May. This new company seems to be silently laying off people now in the name of cost cutting and likely be trying to raise next round of funding although they previously raised previous round in Aug-2022. Although right now it's more of they need me (my role, I'm the only person of this role) more than I need them, I'm 70% confident that I might not be impacted, but the 30% chance is keeping me sleepless. What do I do? Pretty traumatized from the first layoff.
