Tired Of Living

My girlfriend told me it's over between us, I thought about it and decided that life without her is meaningless, so I
decided to kill myself.

I drank Lacasera wit Suya but nothing happened, I proceeded to another level of poisonous concoction, so I prepared Turkey and Gizzard with strawberry juice and lot of fresh tomatoes, yet nothing. I ate cake, chocolate mixed wit ice cream, still I didn't die.

I'm so confused and tired right now because I just finished eating fried rice wit Maltina and fresh fruit salad but nothing happened. What should I do to kill myself?

I need advice, please!!!
