A letter to my suicidal friend

The letter

How do I make it known to you that I love you?
How do I make you feel the amount of love I have for you?
Why have you decided to leave me? I hope this will convince you.
We have so many memories together, we have sacrificed a lot for each other,I'm literally crying at the thought of loosing you.
So if you go what next? I know that the life goes on but vacuum in my heart will never be filled.
Knowing that no amount of gifts ,money or friends I have or will have can replace your presence in my life alone is scary. Please don't leave me with just memories,please don't carry out with this selfish thought.
You've become a part of my life already and one I'm scared to loose at that, I've learnt a lot from both consciously and unconsciously.
Remember the times we  cried ,laughed,fought,sang,played,argued and talked ,can that honestly be replaced?
If you think even for a second that in my next life I'll meet you again then that's a lie because even that version of you would be fake.
Dearest, please let's grow old together. No matter how bad life treats you never forget that we ride together and we die together.
I can't guarantee that if you decide to live life would be easy on you, I can't guarantee that you happiness but you know whatever you're facing someone has gone through it before, the only difference is how you handle it and I know that you are strong, you've fought for so long why give up now knowing fully well that there's always a light at the end of the tunnel.
You are one in a million ,I mean where would I find another you on the face of the earth .
Can you please put yourself in my shoes for a moment, can you please consider my feelings. Imagine how you'd feel if it was the other way around ,scared right?
Loosing you would be disastrous, I know my world wouldn't be the same without you because it got better when I met you.
The  love I have for you overshadows my fear of loosing you, I will not forgive you if you kill yourself.
Do you know the worst feeling after loosing a loved one. Its the one you feel when you leave your house and notice that life goes on ,that every one else irrespective of their issues is trying to survive, that nobody even notices that you've lost a loved one and you're grieving. At that point you'd want to run a thousand miles per minutes, you'd want to scream out your lungs ,you'd want to stop every one from moving ,you'd be mad at the world for not noticing that a part of you is gone  ,you'd be mad at how everyone else will move on so quickly and heal from the hurt of loosing you and you're still hurting,still grieving, carrying a heart which gets heavier by the day but you know what that's life and that realization is so exhausting.
I for one know that I can literally run mad if I loose you and the world goes on.
Please don't leave me with memories of your smile, laughter, and all our adventures together.
I need you the world needs you and we can't keep on loosing good people like you.
So please stay,
I love you now always and forever.

What if I'm the suicidal friend?
