No words would do

 No matter what you say, no matter how hard you try to put it into words, it just doesn't get through.

I guess if a mind is already set in stone to not accept what you say, then whatever you say would not matter. It would not matter at all.

As strong as I try to be, I'm still weak. 

I'm not that strong to continue fighting towards a journey where I feel like I'm alone.

Of all the phases in life, I have never felt as lonely as I do now.

In the past I felt like I have a few faces I could turn to, but day by day the number of faces that I feel confident enough to not feel like a burden to, slowly reduces to a number near zero

Yes one, there's only few I'm confident enough to expose myself, to be 100% myself, to be totally clingy and not feel like a burden.

And if I lose them, I'm pretty sure I can't stay sane anymore.
