My mom thinks im suicidal help!?

i took 40 benadryl pills and she now thinks that i was trying to self destruct . i have told her that i wasnt , and she wont believe me, she then says "you subconciously were". she thinks im crazy for doing this but im NOT!!!! i just did it to see what it would feel like, i was bored and just did it at night time and thought it would wear off in the morning and nobody would notice, unfortunately, i was still intoxicated in the morning and afternoon the next day, she wanted to take me to the hospital. why does she think im suicidal. im not crazy or suicidal or anything like that , i just wanted to try it for recreational purpose, my mom dont believe me when i tell her that i did it for this purpose
