If i drank and took a benadryl (diphenhydramine) will i die?

I guess that depends: On how much you took of each. I am concerned about you asking for a recipe to die by. I don't know what is happening in your life, that you would ask this. But, what i can tell you is that with help, your life can improve. With hope & with help whatever feels insurmountable now can be overcome. Please get help now. Take care.
