I just want to disappear

I don’t know how to start this but I just want to disappear, disappear from my life, from everything, from everyone. I feel so alone and I can’t talk to anyone personally in my life because it’s hard to admit that I’m struggling mentally. It’s hard for me to tell people I want to disappear from their lives as I fear they will take it personally. 
I’m just tired of my life, I’m tired of the battles I constantly have to face and the struggles it gives me. The idea of disappearing feels like weight is lifted of my shoulders and I can breathe again, the idea feels so calm and relaxing as that is all I’ve ever wanted.. peace. 

it’s easy for me to think that no one will care that I’m gone, no one will look for me or try to search for me but I know that’s no true.
So I stay, I stay to exist another day, to deal with life’s problems and the anxiety i feel with it. Because everyone has to deal with life, why can’t I… 

So I disappear in my thoughts as all I have to escape from everything and everyone.
