Where do I start to express my emotions

I lost the only person who understood me

My sister from another mother the

Person who accepted me with my flaws and mistakes

my heart aches with pain when we

pass each other like strangers

i don’t even recognize my own friend

how do I tell her that the road she is taking will only lead her to pain and heartbreak

the people she takes as friends will

devour her like vuItures

i know I took that road too and it leads to pain and suffering

How do I Warn her ???
