After my girl left me, i always feel like committing suicide. I attempted twice already. What should I do?

my girl dumped me a few weeks earlier. after that i feel like i have failed my life. I just want to end my life and get rid of this problem. I once drank Methyl parathion and stayed in ICU for over 2 weeks and still I feel like doing it so again and again. I don't know what to do and how can i take my life further. Can anybody help me please??
