I have a question to the DEPRESSED!! Please help.......? ?

Okay, if you have been depressed for a long time now, like you always spend your days alone, do you feel like this.. feel like its hard to live on reality? i dunno if am the only one who feels that.. i mean the feeling is just weird.. i am aware that i feel the way that i do coz ive been spending my time alone, my thoughts are mostly about depression, abnormality, blablabla so when i go out my house i feel weird. I feel like im somwhere. I feel lost in the crowd. I just feel weird. and the thought makes it even hard for me put my finger on what is real. Have you ever felt that??
