I think this is a very sweet poem, though the swear seemed to spoil it a bit. I definitely liked:
"I’ll be there when you want to talk about youserlf sincerely
from your heart…
I’ll be listening every piece of you."

You do have some small grammar and spelling mistakes to fix, but nothing serious. Regardless, I think it gives the pretense of being friends with someone you can't see or talk to, which I know too well myself.

The end was a bit surprising. You are friends, because you a both kind of weird? A touching poem anyhow.
