i feel like just going to a deserted place

i feel this way all the time,like just go away and let the world have it.Rejection hurts i have experience in it i have had it most of my life.at times i feel like a reject so much,my days are spent alone with no one around to talk to.i have been judged so many times it make me think what i did to deserve this.i am confused to why.i have been away from any type of contact for 2 or 3 days and then you have people asking are you ok?,and then i think to myself no that's why i went away in the first place. and the tears that come from this feeling is very real.to all of you here that feel unwanted i do care i know the feeling and i hope all of are feeling better.
