No meds, till you consult with a mental health professional.
There is no magic, 1,2,3 med. (I know) the best and safest thing to do if you are in crisis is to call a local hospital/911, even get someone to take you to the nearest hospital/behavioural health dept. for immediate professional attention.
If you are seeing a therapist and/or pdoc at the present time, consult with them ASAP.
Hope you'll consider this, believe me there is hope out there as well as help.

Please take care,
