You would want to connect with a therapist who treats acute stress disorder to help you with the most recent symptoms that you're experiencing after the earth quake. Going to the hospital (if you're wondering about hospitalization) will not necessarily result i being hospitalized unless there is imminent danger to self or another evident.
You would benefit from the therapy and while your doc is away you could at least have someone assist you.
If you need medication only for sleep/anxiety any doc can prescribe it. There is also over the counter options like Magnesium, L-Trytophan and Gaba to new a few.
